Issue

Migration of Google Chat and Google spaces History are not included in MS FastTrack migration. We need to determine whether to accept or to pursue an alternative approach.

Recommendation

Option 3 : Not to Migrate history, because migrating with tool doesn't give a consistent result and is deemed hardly usable for end-users. Migrating with Google Takeout exports to Json file and reading this requires a Open-Source tool.

Background & Context

Chat and Spaces history can be valuable for Syensqo for Historical reasons.

Transporting this history to the Microsoft system is not straight forward activity and requires additional effort.

Assumptions

Chat history doesn't hold legal grounds

Constraints

No consistent result with migration tool.

End-user self extract and import is not an option.

Change management impact

Impacts

If history not migrated - loss of history.

Business Rules

Options considered

Option 1: Migrate Data With Cloudiway

Option 2: Migrate Data With Google Takeout Services

Option 3: No Migration + no Takeout export and disable chat

Option 4: don't disable Google Chat

Evaluation

Criteria	Option 1: Migrate Data With Cloudiway	Option 2: Migrate Data With Google Takeout Services	Option 3: No Migration + no Takeout export and disable chat	Option 4: don't disable Google Chat
Technical Feasibility	Tool not Mature, lots of trial and error. Slow Support. Even if you only export, empty group chats are created.	User Action, cannot be done from Admin Exports data to Json file and reading the exported data requires Open-source tool	Low - disabling Takeout	Migration: N/A - no actions to perform Sunset of GWS: potential issues with chats still in use
User Impact	Chat can be exported as HTML and in a second stage can be imported in Teams One on one chats are imported as seperate group chats and not in the one on one chats. (history will be stored in a different conversation than 1:1) User mapping doesn't always work.	Exporting the chat history + spaces is a user action, technical and source of error Reading the exported data requires Open-source tool Chat history not imported in Teams Format is degraded (ex: pictures not available)	Loss of history, without workaround	Coexistence issue: chats coming to both platofrms (potentially from the same people) User can check history until license is revoked. No incentive to use new Technology
Security & Compliance	SIP Compliance of Cloudiway TBC	Watchpoint on using freeware Watchpoint on what users could do with the extracted data (Takeout can be restricted to some services in particular)	N/A
Time to implement	Procurement delay & SIP delay	Depends on User	N/A
Support impact	High as above constraints will cause user issues and aggravation	Low as pretty straight forward procedure	More tickets expected of users requiring access to their chat history
Operational Complexity	Tool and connection needs to setup and maintained during migration	Open-source tool need to be assed by security + Versions have to followed up Change management workload around users instructions for Takeout extracts	Any specific / critical case has to be managed centrally as users can't perform any action themselves
Cost	License(230,000€) + effort(100,000€)
