I am trying to upgrade TFS2018 to Devops2020. I ran the Devops2020.exe and it appears to have upgraded my TFS-Configuration db because Devops2020 recognizes it and the collection is started. It did not seem to appear to upgrade my other two collections. I cannot start either collection. I get the following error: The host cannot be started. the servicing needs to be scheduled and completed before the host can be started.

My databases still have the TFS_prefix on the db's in SQL server how ever I created a Test collection and the db is prefixed with AzureDevOps_.
