One-One Chat Messages Migration From Teams To Teams

This article explains how One-One chat are migrated between 2 Microsoft 365 tenants and injected directly into the chats.

Check the One-One Chat Messages Migration Tool for more information about the product.

How does it work?

Migration Link

One-One chat messages (private messages) are considered private data by Microsoft Teams and cannot be accessed by the company or by an administrator. The only way they can be migrated is with the permission of each individual user. Users who do not follow this process will not have their One-One chat  messages migrated.

For performance reasons, only the 1000 most recent messages are injected into the chats and the oldest messages are stored into an HTML file uploaded to the user OneDrive.

This default behavior can be overwritten into the Global Settings.

The process is the following:

• The administrator of the migration sends a link by mail to every user.
• The email is sent by the platform and contains a self service migration mail.

Migration

The user clicks on the link that he has received by mail.

This redirects him to Microsoft 365 and requests him to authenticates.

Once authenticated, he authorizes the Cloudiway platform to access his private messages.

If the user accepts it, Microsoft 365 generates a user token and sends it back to Cloudiway. Cloudiway will then start the migration with this consent token.

The following steps show how to perform the migration.

Under Group User List /  MIGRATION , click on the Get List option:

Consent Process

This process has to be done only one time. Once the platform has the consent, the administrator of the platform can start delta passes from the user list without involving anymore the end user.
