Back in July 2018, Microsoft released new functionality to Microsoft Teams that would migrate existing contacts and contact groups that you have configured in your Skype For Business client into Teams. Specifically, the release details were:
Bring your Skype for Business contacts to Teams When your organization moves from Skype for Business to Teams, your contacts will make the move with you. To see them, once you’re in Teams, click Chat on the left, then Contacts at the top.
During a recent migration from Skype for Business on-premises to Teams, though, I encountered a user who had multiple groups and contacts but none appeared in the Teams client. The fix was quick and painless.
When uploading files into Microsoft Teams, there are a few gotchas that I wasn’t aware of until I recently tried moving some data into a new Team. I thought sharing these may be of use to others as well.
If you are moving lots of data, you can only upload 10 files at a time
The files have to contain content…no empty text documents, for example (although not sure why you’d need these anyway.)
By default in the Teams client, you will lose any folder structure if doing a wholesale move of files. You can manually create the folder before copying files or use a workaround
