In Debian, using tor-instance-create and systemd, there is a separate directory, /var/lib/tor-instances
You'll need to copy both /var/lib/tor and /var/lib/tor-instances to preserve the keys, and /etc/tor to preserve the configs.

That said, please consider rotating keys when you move (that is, only copying /etc/tor).

If your old relay or those keys were ever compromised, you'll have a fresh start.
And even if it wasn't, some of your network reputation will be reset when you move IP addresses anyway.
