We are preparing to move our server over to some new hardware, so I decided to take advantage of unused hardware and test how things work when doing a disaster recovery. Things have pretty much gone fine following Network Edition Disaster Recovery - Zimbra :: Wiki , with a few surprises along the way due to (known) bugs in the particular release I am running.

One thing that I noted didn't get restored as part of the process was the SSL certificate. It doesn't look like the certificates are backed up as part of the standard backups for NE.

Is backing up the contents of /opt/zimbra/ssl/zimbra/commercial sufficient to complete the picture? Then follow up on the restoration side by using the instructions in Commercial Certificate in 5.x - Zimbra :: Wiki ?
