But copying queue files is not recommended. That takes some care
to get right. It is better to relay any queued mail from the old
server to the new, or just turn off the inflow of new mail into
the old server and let the queue "drain" until it is empty.
Don't forget:
# postfix upgrade-configuration
after copying old configs to a new server. If you're on a Debian
system, that's made more difficult by Debian's failure to ensure
that "postfix-files" corresponds accurately to what is actually
installed. You might need to adjust $daemon_directory/postfix-files
to match reality.
