Forwarding (19 pending): Mark (vervecoffee.com admin) will configure the remaining forwarding rules via domain routing in the Coffee Admin Console. Last checked May 11, 2026 — no changes since original audit.

N/A = account is not in scope for that migration component (TBU, No Transfer, and Functional accounts are excluded from calendar migration and forwarding setup until a Japan target is confirmed or the account type requires it). Orange rows = active discrepancy requiring manual resolution before that account's migration can be marked complete.

Personal Drive Hub — Shared Drives (VCR-*)

27

Shared Drives created

22,776

Files copied

0

Failures

27 personal Shared Drives created on vervejapan.com — one per Coffee user. Each drive is named VCR-{coffee-username} and contains a full copy of that user's Coffee My Drive. Files are owned by the drive itself (not the Japan user), so they will survive Coffee account closure. Both the Coffee user (as fileOrganizer) and Japan user (as organizer) have access.

Ownership model: In a Shared Drive, files are owned by the drive entity — not any individual. Even after Coffee accounts are decommissioned, the Japan user retains full access as organizer. The Coffee user's fileOrganizer membership can be removed at any time after cutover.

Next step — cleanup: Once Ken and Mark confirm files are visible and correct in the Shared Drives, trash the old Japan My Drive copies (from the original migration). Those copies are now redundant. A 30-day trash window provides a recovery buffer before permanent deletion.

Google Apps Script projects (require re-authorization post-cutover)

ken@ has 8 Apps Script projects. kazuaki@ has 6. These scripts will stop functioning after the Coffee account is deactivated and must be re-authorized under the new Japan account. Scripts should be re-opened in the Japan account's script.google.com and re-authorized before cutover if possible.

Messages migrated

Google does not provide a supported migration path for Chat history. Google Workspace Migrate — Google's own domain migration tool — does not cover Google Chat. There is no official export API, no cross-domain import endpoint, and no Google-provided tooling to move message history between Workspace domains. Workarounds exist but require extensive custom development and are costly to implement. The standard approach is to create new spaces on the Japan domain and accept that historical threads remain on Coffee accounts while they are still active.

Additional Development Pricing request required for manual injection of history.

Remaining Items

Needs Ken or Mark decision

Item	Detail	Priority
Email forwarding — 16 accounts	16 Coffee accounts have no forwarding to Japan. Two options: per-user setup (Japan users verify) or domain routing rule (Admin Console, no user action). Decision needed before cutover.	Before cutover
ebisuhq@ forwarding destination	Currently forwarding to [email protected]. User map says [email protected]. Confirm correct target.	Before cutover
TBU accounts (3 users)	moekotagawa@, taitohirakue@, yuzunatamura@ — Japan email addresses not yet assigned. Drive and calendar data not migrated for these users.	Before cutover
Admin app email updates	Slack, Figma, Notion, LayerX, Canva, Zoom, Docusign, Zapier, Miro, tl;dv, Make, TableCheck, Wi2, Soundtrack, Notion Calendar. Admin for each platform updates member email before deactivating Coffee accounts.	Before cutover
Google Chat spaces	Determine which Coffee-domain Chat spaces should be recreated on Japan domain. Japan users need to be invited to new spaces.	Ken direction
japan-pr@ group members	Group exists but has no members. Ken to assign if group is still needed.	Ken direction
RETAIL drive — non-OML member access	Shortcuts in RETAIL drive point to OML Inc. folders. Users who are not OML drive organizers will see shortcuts but cannot open targets. Ken to grant OML access as needed.	Ken direction

Post-cutover (Japan team)

Item	Who	Detail
Apps Script re-authorization	ken@, kazuaki@	Open each script project in Japan account, re-authorize. Scripts will stop working when Coffee account is deactivated.
Device sign-ins	All users with iOS/Android/macOS	Remove old @vervecoffee.com account from device, add new @vervejapan.com account.
User-managed app sign-ins	Individual users	OpenAI, Uber, PayPay, Dropbox, Kahoot, Agoda, Acnestudios, Canon, Lumin PDF, Shopify, Indeed, YouTube TV — users sign in with new account.
Revert sharing allowlist	Mark (Admin Console)	Remove vervecoffee.com from Japan domain's sharing allowlist after Coffee accounts are no longer needed.
Delta sync	Scheduled	Run final delta sync of any files modified after the initial migration date, immediately before cutover.
Deactivate Coffee accounts	Mark (Admin Console)	After confirming all users are operating on Japan accounts. Retain accounts for a transition period to preserve forwarding.

Open Items — Pre-Cutover Checklist

P0 — Immediate (blocking cutover)

Item	Owner	Detail
Fix ebisuhq@ forwarding destination	Admin Console	Currently pointing to `[email protected]`. Correct destination is `[email protected]` (already a verified forwarding address — no re-verification needed). Update forwarding rule, confirm with a test send.
Confirm roastery-kamakura target	Ken / Mark	CSV spec shows `[email protected]` — the "P" may be a data entry error or a first-name initial. No account or person matching this pattern exists in the migration data. Confirm the correct destination before any routing is set up for this account.
Resolve TBU accounts (3 users)	Ken / Mark	moekotagawa@, taitohirakue@, yuzunatamura@ have no Japan email assigned. Decision required: (A) assign Japan address and migrate, (B) keep on Coffee, or (C) terminate. No migration work is possible until this is decided.
Set email forwarding — 15 Coffee accounts	Admin Console	Accounts: aoitakatsuki, hikarusakigawa, kazuaki, keitaro, kento, masashi, miku, naoeguchi, rikako, rin, sanamiyamura, stetsuya, taiga.katsuragawa, yukiko, yoyogi. Two approaches: domain routing rule (faster, no per-user verification) or per-user setup (Japan users click verification email). Decision from Mark needed on approach before this can be completed.
Update Slack — 14 users	Slack Admin (Ken)	Update each user's Slack account email to their Japan address before Coffee accounts are deactivated. If done after deactivation, affected users lose Slack access. Slack Admin panel → Members → Edit each user's email.
Update LayerX — 8 users	LayerX Admin	Update user login emails in LayerX admin to Japan addresses before Coffee account deactivation to avoid locked-out expense approvals.
Update Figma — 4 users (ken, kazuaki, keitaro, miku)	Figma Admin (Ken)	Reassign seats or update member emails in Figma Admin Console. If SSO is enforced, also update the SSO identity mapping.
Update Wire & Wireless — 3 users (kento, rikako, rin)	W&W Admin	Update account email in Wire & Wireless admin portal for these 3 users before Coffee account deactivation.
Update Notion — 2 users (ken, taiga)	Notion Admin (Ken)	Update member emails in Notion workspace. Ken also has Notion Calendar as a separate OAuth token — handle both in the same session.
Update Canva — 2 users (miku, naoeguchi)	Canva Admin	Reassign team member emails in Canva Teams. Check whether designs are tied to the Coffee Google login and transfer ownership if so.
Update Zoom — 2 users (ken, stetsuya)	Zoom Admin (Ken)	Update account email in Zoom Admin. If Zoom is SSO-linked to Google, update the SSO attribute mapping. Verify recurring meetings are intact after update.
Update ken's single-user apps (8 apps)	Ken	Docusign, Make, Miro, TableCheck, Zapier, tl;dv, Soundtrack Your Brand, Notion Calendar — all linked to `[email protected]`. Make and Zapier are highest urgency — active automations break the moment Coffee account is suspended. Update Google Workspace connection module in each and re-authenticate.

P1 — Before cutover (important)

Item	Owner	Detail
Google Chat — decide fate of Coffee-only spaces	Ken / Mark	52 Chat spaces exist only on the Coffee domain. Ken/Mark need to review and decide for each: recreate on Japan domain, export/archive, or abandon. Japan users added to recreated spaces will see new messages only — older Coffee-only history is not transferable.
Run final Drive delta sync	Multipoint	Delta sync script is ready. Run within 24 hours before cutover. Sequence: delta_sync.py → rewrite_perms.py → anon_links.py.
Notify all users of cutover date	Ken / Mark	Once cutover date is set, notify all 24 users with: exact date/time, instruction to sign out of Google on all devices and back in with Japan address, and a list of personal apps each user needs to update (Uber, PayPay, Dropbox, etc.).
Verify 8 cafe location inboxes	Admin	Send a test email to each cafe location address on vervejapan.com and confirm receipt. Confirm delegation or shared access is set up for whoever manages each inbox.
Verify [email protected] is functional	Admin	Confirm test email delivery. Verify any invoicing or billing system is updated to use this new address. Set up delegation to appropriate team member.
Contacts retry — 3 users with API failures	Multipoint	shinjuku@ (11 contacts), roppongi@ (4), rikako@ (1) — failed due to duplicate display name in Google Contacts API. Manual recreation or retry with deduplication needed.

P2 / P3 — Post-cutover

Item	Owner	Detail
Re-authorize Apps Scripts	Japan team	26 scripts across 7 users must be re-authorized after Japan accounts are active. Priority: ken (11 scripts), kazuaki (6), rikako (4), others. Open each script in Apps Script editor, run once, approve under Japan account.
Device re-authentication (~18 users)	Japan team	All users sign out of Google on iOS/Android/macOS and sign back in with Japan address. MDM/managed device users should coordinate with IT.
Personal app migrations (OpenAI, Uber, PayPay, Dropbox, etc.)	Individual users	Each user updates personal apps that use Google SSO or Coffee email. Check Google Account → Security → Third-party apps for a full list per user.
Export Chat history for abandoned Coffee spaces	Admin (if Ken/Mark decide)	For any Coffee-only spaces not recreated on Japan domain, export conversation history via Google Takeout or Admin Vault before Coffee account deactivation.
Remove vervecoffee.com from Japan allowlist	Admin Console	Remove vervecoffee.com from the Japan domain's Drive sharing allowlist after a transition period. Premature removal breaks any remaining cross-domain shares. Recommended: 30 days post-cutover.
Suspend Coffee accounts	Mark (Admin Console)	After all users confirm Japan account is working. Suspend (do not delete) to retain data and preserve forwarding during transition. Confirm no active automations or app logins still depend on Coffee addresses first.

Cutover Plan

This tab documents the sequence and known constraints for the Coffee → Japan cutover. Items labeled Ken/Mark require their decision or action. Items labeled Admin require Google Workspace Admin Console access. Items labeled Japan team are executed by end users after cutover.

Pre-Cutover — Admin Actions

#	Action	Owner	Status
1	Fix ebisuhq@ forwarding to `[email protected]`	Admin	Needs fix
2	Set email forwarding for 15 pending Coffee accounts	Admin / Mark	Not set

4	Resolve 3 TBU account destinations (moekotagawa, taitohirakue, yuzunatamura)	Ken / Mark	Decision needed
5	Run final Drive delta sync (delta_sync → rewrite_perms → anon_links)	Multipoint	Ready, not run
6	Update all admin app email addresses (Slack 14, LayerX 8, Figma 4, Zoom 2, W&W 3, Notion 2, Canva 2, ken's 8 single-user apps)	Platform admins / Ken	Not started
7	Notify users of cutover date + per-user checklist	Ken / Mark	Pending date

Cutover Day Sequence

1️⃣

Run final delta sync

Last capture of any Drive files modified since last sync. Sequence: delta_sync → rewrite_perms → anon_links.

2️⃣

Verify all 24 accounts have active forwarding

Send a test email to each Coffee address. Confirm arrival at the Japan address. Fix any failures before proceeding.

3️⃣

Spot-check shared drive access

5 users across different roles verify they can open RETAIL, CX_DRIVE, and Fender Cafe drives from their Japan accounts.

4️⃣

Test Japan group routing

Send a test message to each configured Japan group (info@, invoice@, wholesale@) and confirm delivery to all members.

5️⃣

Send "switch now" notification to all users

Ken or Mark sends the go-live message. Users sign out of Coffee account on all devices and sign into Japan account.

6️⃣

Add Japan users to approved Chat spaces

For Chat spaces Ken approved in pre-cutover planning, add Japan account members via Admin Console Space Management.

Known Permanent Limitations

The following items cannot be migrated — they are documented here as accepted constraints, not open work items.

Item	Detail
Google Chat history — Coffee-only spaces	Message history in spaces that exist only on the Coffee domain is not transferable to Japan accounts. Japan users added to these spaces see future messages only. Older history remains accessible as long as Coffee accounts are active.
2 calendar events (recurring wholesale) Closed	yoichiro@ — declined this specific recurring instance. Intentionally excluded by migration logic; correct behavior. kazuaki@ — never responded to the invite (needsAction). June 2023 past event, no practical impact. No action required for either.
3 contacts (duplicate display name)	3 contacts across shinjuku@, roppongi@, and rikako@ failed with a Google API limitation for duplicate names. Can be recreated manually in Google Contacts if needed.
Ken's personal Gmail calendar link	The connection between Ken's personal `[email protected]` calendar and his work account cannot be replicated by the admin API. Ken must re-subscribe manually in Google Calendar settings (cross-account subscriptions are user-only).
179 OAuth tokens (all users)	All third-party app authorizations made from Coffee accounts will expire when those accounts are deactivated. Each user must re-authorize each app from their Japan account. OAuth tokens are non-transferable by design.
4 externally-owned Shared Drives	The バクラク drive (LayerX-owned) and the サポトレ drive (Sapotore-owned) are outside the Coffee domain's control. Japan users who need access should request it directly from those vendors.

Open Questions — Ken / Mark Decision Needed

Question	Context
TBU accounts — assign, hold, or terminate?	moekotagawa@, taitohirakue@, yuzunatamura@ have no Japan email. No migration work can proceed for these three until a decision is made.
Which Chat spaces should Japan users join?	35 named operational spaces on Coffee have no Japan members. A full space list is available in the Google Chat tab. Ken should review and mark which ones to recreate or open on the Japan domain before cutover.
Chat history archive for abandoned Coffee spaces?	For any spaces being abandoned (not recreated on Japan), should message history be downloaded and stored before Coffee accounts are deactivated?
japan@ (Verve Japan account) — 90.5GB Drive + 29.9GB email Clarified	Not migrated — no Japan-domain users are mapped to this account and no destination exists in user_map.json. Content remains on the Coffee domain. If Ken or Mark identify an owner on vervejapan.com, a separate migration plan can be scoped at that time.
Japan Drive trash (approx. 1,700 files)	Files currently in Japan Drive trash from the migration cleanup are recoverable for 30 days. Confirm date by which trash should be permanently emptied.
vcrjcafe@ — listed as no-transfer but holds a higher-tier license	Spec says no transfer needed. Account has a 1010020025 license (higher tier). Confirm deletion of this account is intentional.
