Moving cluster onto new kit with no downtime
-
Im trying to move a cluster(not sure if thats the right word) of 2 pfsense 1.2.2 firewalls that have carp nad a few packages installed onto 2 new servers. Im trying to do this with no downtime but a 5 -10 min window is probably acceptable.
What is the best way to go about doing this.
I was thinking of upgrading the old servers to 1.2.3-RELEASE then just adding the new servers in as slaves for carp then start removing the old ones.
Or is it just easier to extract a backup on each of the old servers and import this into the new kits plug the network cables into the same ports on the servers and turn off the old kit.

If you already have your boxes setup in a failover pair, just take a backup of each. Then restore the backup to the new firewalls. Then swap out the "old" slave unit with the "new" slave unit. It should work OK between 1.2.2 and 1.2.3, though if they were all on 1.2.3 it might be better.
After you swap out the slave unit, and it shows that it's working OK, then do the same with the master.
The slave box should then take over, and you shouldn't have any downtime. When the new master comes online it should take control agian.

we ended up updating the old slave to 1.2.3-Release then taking a backup of it and dumping it onto the new kit. Made new2 the master and then backed up the the old master, restored it onto the new master checked and we had a working cluster again.
Many thanks
