TFS 2018 ERROR : TF401054

I had restore TFS database 2015(SQL 2014) to 2018(SQL 2017) successfully. and remapped it. But I got this error when I try to login to TFS

TF401054: The requested service level property TFS_SERVICE_LEVEL did not match the expected value. Team Foundation Server requires the Dev16.M122.7 service level but the database currently implements Dev14.M113.

I hope you have backups of your databases in a known good state; your best bet is going to be to bring back up a working TFS 2015 instance and then follow modern upgrade documentation.

The basic problem is that your team project collection databases have to be upgraded. Pointing TFS 2017 to TFS 2015 project collection databases without putting those databases through the normal process of attaching them (and thus upgrading them) isn't going to work. In a migration-based scenario, this is typically accomplished via the TFS admin console.

You may be able to go to the admin console and attach the databases, but my recommendation would be to bring up a working instance of your TFS 2015 environment and start from scratch.
