We are currently on 6.0.9 and looking to upgrade. Need to be able to wildcard policies which is in versions 6.2.2 and above. Thinking of doing a double firmware jump up to 6.4.2. Worried as this is our production environment in a hospital and would normally jump to higher revision of the previous firmware branch. However the 6.2.x range seems to have had awful reviews, especially 6.2.4.
On the while 6.4.x in generally seems to be a lot better reviewed than previous branches. On the whole would people recommend this firmware despite still being in an early release? If we do a double jump though we will not be able to downgrade the standard way of switching partitions. But if we are going to upgrade I cannot see the benefits of moving to 6.2.x. I assume 6.4.x has been released so close to it due to issues with that branch.
I think 6.4.2 is better then 6.2.4, but possibly neither a ideal
Be careful about the wildcard policies, they might not work as you expect, they don't work for all traffic
