i have 2 servers one have TFS 2015 and Other one have 2018. I tried many times to restore 2015 to 2018, But not success. I can't stop 2015 server to take backup Because it is a live database. So i got backup from SQL server and try to restore to SQL 2017.
Database successfully restored but I can't login to the TFS.

Error : 1
TF30046: The instance information does not match. Team Foundation expected a4ad68c8-f8ab-4088-9d75-dc9ac4e8198b which was not found. Please contact your Team Foundation Server administrator.

Error : 2
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.
