Hello Jonathan, Given that the message seems to be coming from [around here](https://github.com/gocd/gocd/blob/1278474dcd8b2e90c0f19fc15098c279274141cb/db-support/db-migration/src/main/java/com/thoughtworks/go/server/database/migration/DatabaseMigrator.java#L61), there could be more information in the logs. It's hard to say what the problem is without more information.
> My understanding was that running this tool would only write to the target database with no impact on the source. That is a reasonable expectation, I feel. However, one of the reasons [the first steps in the documentation](https://docs.gocd.org/current/installation/upgrade_to_gocd_20.5.0.html) mentions backing up and stopping the server is to make recovery easier. I don't know what happens if you run this against a *running* GoCD server. I wonder if permissions got changed, or something like that. Won't know without more information from the logs.
