How to migrate 2 team collections from tfs to one organization in azure devops services?

Question

From what I've read that for each collection will be migrating to one organization. Is there any suggestion or other way to migrate to solve this issue?

Answer 1

By default we cannot achieve that by the official migration tool. Since each collection maps to one database in Azure DevOps Server, and the migration process works by importing an entire collection. So, each collection will be migrating to one organization separately.

As a workaround, you can try to create new projects in the migrated organization, then manually migrate the projects, of course it will has some limits.

• For the sources,you can import the repository directly, please see Import a Git repo for details.
• For work items you can use the third-party tools or extensions or Microsoft Excel to do that, however the history will be missed. You can reference this thread: Move bugs with history and attachments to a new project
