[tor-relays] Relay migration: best practices?

[nusenu]

If the IP and uplink speed does not change you can simply
- stop tor at the old server
- migrate the IP
- migrate the tor config and the entire datadir
- ensure the datadir is removed on the old server to avoid accidentally running more than one tor instance with the same key
- ensure datadir permissions are set properly
- start tor on the new server

Compared to only copying the key files, this will avoid tor assuming it is a new relay without prior history.

kind regards,
nusenu
