How to Migrate Teams Chat History??

Migrate Microsoft Teams from one tenant to another manually
Migrating Microsoft Teams data to another tenant manually involves multiple steps and a ton of heavy lifting on the part of IT.

Technically, there’s no easy, out-of-the-box way to migrate Microsoft Teams between Microsoft 365 tenants. But you can move some of the underlying components, such as the files stored on the associated team SharePoint site and group chat and channel conversation history stored in the team’s Exchange mailbox.

While there are a few different ways you can go about doing this, we’re going to walk you through one of the most straightforward methods that don’t involve any third-party tools.

To migrate your Microsoft Teams to another tenant manually, you need to:

Re-create the teams you want to migrate to the destination
Add all of the correct users and permissions to each team
Download the contents of the associated SharePoint team sites and upload them at the destination
Export conversations from the team’s Exchange mailbox, then import them at the destination as a document
