Hi Dan,
BitTitan and Quest both offer options to migrate Teams from one tenant to another.
BitTitan has a custom discovery script to help you discover content. Tony Redmond has also created a Teams discovery script which is helpful to identify active Teams versus inactive ones.
I just finished performing a similar discovery effort for a customer and it took 60 days to complete full discovery because they had PowerBI, Flows, and Microsoft Dynamics, not to mention Teams, OneDrive, SharePoint, and Identities to consider.
Hope this helps.

Hi Joe Stocker ,
Thanks for the pointers. I will have a look.
Did you perform the discovery only with those tools?
Office 365 can be overwhelming, even for me doing Administration since years. In that new clients tenant, nobody ever thought about restricting the use of O365 Apps, tools, functions or even considered security groups and such. So there's a lot of "let's try this nice App and then forget about it again". That leaves stuff laying around.
Migrating that chaos as such is not advisable. I told the client, but he does not (yet) realize what a migration to a new tenant will require. To say the truth, realistically, me neither...

No, those tools were just some of what we used to perform full discovery. Here is full list of the various administration portals to investigate, which will then lead you into deeper discovery.
1. Security and Compliance Center http://protection.office.com
Note: The Security and Compliance Center will be going away eventually and replaced with these two new portals which do not yet have 100% of the content from the combined portal
a. Security Center http://security.microsoft.com
b. Compliance Center http://compliance.microsoft.com
2. Old O365 Portal: http://portal.office.com
3. New O365 Portal: http://admin.microsoft.com
4. Exchange Online Control Panel http://outlook.com/ecp
5. Other Portals SharePoint, Yammer, Teams, Dynamics, PowerBI, PowerApps, OneDrive, Flow can be accessed from https://admin.microsoft.com/Adminportal/Home#/alladmincenters
6. Azure Web Shell http://shell.azure.com (This is protected with the Conditional Access Policy that I referenced in our meeting).
7. Azure Portal - https://portal.azure.com
