I am looking at migrating the source from SVN to Azure DevOps. I would like to know if you have done similar migration in past so that we can take help from you during the migration process. I am also interested in knowing the migration strategy that you will follow for such migration. We already have an Azure DevOps instance.
Yes, such migrations (including mirrored ones) have been done many times before and this approach was used by many of our clients. Basically, SubGit is able to deal with Azure DevOps the same way as with any other remote Git service, we have a guide that describes such a setup:
It describes GotHub as an example, but the approach is the same for any remote Git repository accessible over the protocols supported by Git, so ti works for Azure Repos, too.
Hope it will help.
