Migrating data to a new prometheus server

[Justin Poole]

I have an interest of migrating our primary prometheus server to a different instance class. Initially I went down the path of lifting all data to the new server directly using rsync but now I'm thinking there must be an easier way.

Is federation the answer here? Is there a federation rule that would fundamentally turn a prometheus server into a "slave" of another?

If this isn't possible then any guidance in terms of how I sync the data to the new server would be greatly appreciated.

Thanks for the great monitoring tool, and any help I can get!

Your options are either rsync, or turn on the new server and wait until it has enough data for you.

Federation does not help at all here, as it only returns a snapshot of the most recent sample.

I'm seeing this on my most recent rsync when trying to start the new server. Reading through the code now to try and find what file is can't find. Do you know offhand?
