We’re moving from one server to a newer one.
I’ve upgraded to 2020.3.1 (on an unrelated note, it either dropped some of my bindings or it’s forcing a redirect to the configured domain, instead of accepting connections on any domain as long as the port matched).
After that I’ve moved the database to a new SQL Server and then installed a fresh 2020.3.1 instance on a new Windows server. When I copy the master key straight from the Octopus Manager to the installer, I get the following error: “Please enter a valid master key for the existing database”.
I’ve triple-checked it by now. It’s valid.
