I am planning on updating our OES iPrint server (not the iPrint appliance) from SLES 11SP4/OES2015 SP1 to OES 2018. I want to back up the iPrint data before the upgrade so if something goes sideways, I have some way to recover. I see that ipsmd has a 'restore' option but I don't see a backup option. What is the best way to back up the iPrint database and other files so that I can restore them if the OES2018 backup fails?

By the way, out of two servers that I have upgraded to OES2018, one worked fine, and one required me to open up a support incident with Micro Focus. Not a great track record.
