What does & does not get migrated
In General
In general, you can assume if its not listed below; that items and settings will move seamlessly to the new Syensqo Google Workspace. The most widely used items not moved and/or negatively affected, are listed below; with special apps/data types listed further down under special topics.
Gmail
Trash/Spam: Email items in both of these are not moved
Any Solvay delegates are removed from Syensqo user and shared mailboxes
Calendar
Calendar sharing
Any calendar sharing with Solvay users will be downgraded to Share Free/Busy only. This includes full calendar delegation
Secondary Calendars
Secondary Calendars are not migrated and must be manually exported before the cutover; and imported after. See instructions here: Exporting/Importing Your Secondary Calendar
Room bookings
All events in your primary Google calendar are moved as part of the cutover; however, any room bookings in those events are lost and must be re-invited by event owners once the cutover is complete.
Chat
Group Chats
All Group Chats are not migrated and cannot be retained.
Chat Spaces
Any Chat spaces owned by Syensqo users; will not be migrated and all content will be lost. To ease in recreating them; you can export the Space members lists from within the Space's Manage Members screen, pressing the copy icon (see pic)
Solvay and 3rd party owned Chat Spaces are unaffected by the move.
Google Drive
Most My Drive and Google Shared Drive files owned by Syensqo users will be moved on March 26th without changes to how they are accessible (ie. links, bookmarks, Drive attachments will all function normally.) However there are two notable exceptions:
Transition from Solvay to Syensqo owned Drive files (STARTING MARCH 10)
This affects a small subset of Syensqo users, still collaborating in Google Drive with Solvay. If you believe you are affected; instructions on what to expect and how to work are here: Loss of access to Solvay owned Drive files
Sharing access with “Anyone in Syensqo”
Any item you've set to share with “Anyone in Syensqo, will be reset on March 26th to Restricted; meaning only users/groups specifically listed in its share list will retain access. You can set sharing back to Anyone in Syensqo after the migration.
Likewise, If you find that you cannot access a Drive file you previously could and are presented with a You need access sharing screen like the one below; its likely that your lost access was based on this or a similar sharing rule that was cancelled by the move. You can request a new share to reestablish access.
What to do/expect before the cutover
Google Contacts/Syensqo Company directory
Between March 24-26, users will temporarily lose access to the company directory. Access to your own Google Contacts will not be affected.
Google Calendar - Export any secondary calendars you wish to keep
Exporting/Importing Your Secondary Calendar
How to work during the cutover
The cutover will start on March 26th at around 12h00 (noon) CET. At that time you should... ...continue to work normally. You don't need to log out or interrupt what you are doing. In fact, you likely may not notice anything has changed. You will receive an email update once its complete; with some notes about what to do first and some temporary odd behaviors that you may (but probably won't) notice.
What to do after the cutover
IMPORTANT: Immediately re-invite meeting rooms to Calendar events
All your calendar events will migrate automatically, however any room bookings in those events are lost and must be re-invited by event owners once the cutover is complete.
In other words, following the cutover; all room calendars will be empty and it is imperative you re-invite them to your meetings as soon as possible once you are notified the migration is complete, around 16:00 CET on March 26th.
We ask that if possible, once the cutover begins on Wednesday March 26 at 12:00 CET that you delay booking rooms for new events until Thursday March 27th; to give fellow colleagues the time to rebook existing meetings. Scheduling conflicts will invariably arise; please be considerate.
Set your working locations/hours
Import secondary calendars
If you exported any secondary calendars before the cutover; follow these instructions to recreate them: Exporting/Importing Your Secondary Calendar
Recreate Chat Spaces
As Chat Spaces are not migrated with the cutover; recreate any that you need going forward
