Nope, it is not good enough to just copy the files. If you move
Postfix queues across file systems it is safer to move all (incoming,
active, deferred) queue files to the new incoming queue.

Postfix queue files are based on the file inode number plus time
of arrival in microseconds. If you just copy files you can lose
mail.
