We have a pfSense 2.4.4CE that we want to upgrade to the latest 21.02_1. My question is this. IF things go wrong or don’t function properly, will the restore from Backup do the OS also? If not, how could we get back to the 2.4.4CE to then do the restore?
This of course is productions with HA being heavily used.
@LTS_Tom Thank you so much for the fast response. That is what I was thinking was going to be the case. Do you by chance know where I might get my hands on a 2.4.4CE installation? Appears Netgate doesn’t allow you to go that far back.
Nothing worse than an upgrade breaking everything. I’ve been there and only use pfSense as a VM since I can take a complete snapshot prior to upgrades. It’s smart to have a copy of the firmware prior in case you have to rebuild.
Thank you both. I appreciate the assistance. In a perfect world, I wouldn’t have to worry about going back. But seeing how all production runs via this pfSense. I kinda have to plan for everything.
