Hi,

 

I'm currently investigating possibilities for migrating Teams to a new o365 tenant. Issue that I'am having is the chat history in Channnels. I know this is stored in a hidden folder "Team Chat" in the groupmailbox for the team. However I can only find messages from internal users. Guest access is enabled on the team and guest contributed to the chat. These messages do not appear in groupmailbox. Is it possible to migrate all conversations including guest messages from channels to a new tenant? 

 

Thanks.

At this time there is no Microsoft supported way to migrate Teams from one tenant to another.

There was a known issue with preserving Guest contributions, @Tony Redmond might be able to provide some more insight/recent news on the subject.

Solution

It's a known and acknowledged gap that guest contributions to chats are not captured for compliance purposes. My speculation is that because the guest does not have a mailbox within the tenant, Teams (or rather, the current code) cannot create the items. It's a work in progress...

Ok thanks for the input. Looks like I will have to wait until a migration of conversation history is possible.

let me know how can i migrate one team tenant to another team tenant@Camille Bovy 

@jobsy2019  Since this conversation started, a number of ISVs have launched T2T products for Teams. I cover the basics in https://www.petri.com/bittitan-introduces-cross-tenant-teams-migration (BitTitan) and https://office365itpros.com/2019/08/19/avepoint-teams-backup/ (AvePoint), but there's also Quadrotech's Cloud Commander product to consider. All use the same Graph-based API from Microsoft.
