I have tried to move zimbra from one server to another doing the following:

successfully move the directory to the remote location
-scp -P [port] -r /opt/zimbra user@remoteservername:./zimbra destination

-Install zimbra on the new server

Remove the zimbra directory from the new server using the following command
-rm -rf /opt/zimbra

Sync the zimbra directory that was copied to the new server
rsync -avr zimbra /opt

reinstall zimbra as to upgrade it

and had an error message...Below is the error message

Error: assertion '-r /bin/mysqld_safe' failed

Please tell me what is the best way to move my zimbra to a more spacious server.
