My VPS host https://horizon.wikimedia.org/project/instances/43d3e9f2-b7d5-4a51-92b6-6a636839d66f/ is running debian buster. What's the best way to migrate to a newer image? I've already spun up a bullseye instance https://horizon.wikimedia.org/project/instances/ffae23a6-47bf-4c76-bfd2-d6b7d2cf495b/. Is there some easy way to move all my data to the new machine, or should I just copy it over manually with scp or something like that?
