Follow these methods to do
Microsoft Teams migration 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 doesn’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 at the destination
Add all of the correct users and permissions to each team
Download the contents of the associated SharePoint team sites and upload at the destination
Export conversations from the team’s Exchange mailbox, then import them at the destination as a document
Step #1: Re-create the teams you want to migrate at the destination
Before you copy any Teams content, you need to create teams in your new Teams environment so that content has a destination.
Essentially, this means re-creating the structure of your source Teams—including the channels and tabs within each team. Sound time consuming? That’s because it is. But you’re only getting started.
Step #2: Add all of the correct users and permissions to each team

Once you have the scaffolding set up in your new Teams environment, you need to populate it properly. That means adding all of the correct users and permissions to each team.
Assuming you followed migration best practice, you should already have all your users added at the destination Azure Active Directory. So what you’re really doing in this step is inviting users to join the same teams they were members of in the old Teams
environment.
To invite bulk users to a Microsoft Teams team, you need to:
Extract users/permissions to a CSV file
Modify the domains associated with each user
Add users to the destination teams from the CSV file
Modify permissions within each team
Extract users/permissions to a CSV file
The first thing you need to do is generate a list of details about your existing Microsoft Teams. There’s no way to do this using Microsoft tools, so hopefully you’re comfortable with scripting.
