Contacts sync on migration

New Contributor

Hallo Community,


my users keep asking , what happens with the already created contacts in Teams (Islands Mode) when migrating from SfB OnPrem to Teams Only. I did not find a good documentation from Microsoft. Can anyone explain that process and if the contacts get overwritten?

@M-4corn The existing contacts will remain, but a sync occurs as people move to Teams Only that will bring over any contacts added to SfB.

Thank you for the reply.
But what happens to the Contact Groups, if there is a group in SfB & Teams with the same name? Will both be available after the migration to Teams Only?
