Hello, I want to move my v3 onion address to the new server. How can I do? Thanks
Check in your current torrc file (/etc/tor/torrc on Linux OS) name of directory where your domain reside. It will be after HiddenServiceDir (/var/lib/tor/... on Linux OS)
Copy that folder to a new server. Check owner (different for different OS) and permissions. Write it to your new torrc file or just copy it if you're moving to similar OS.
