I'd go 5.3.3 with SP2 if you want stability, or wait for 6.1 to drop if you want to be on the forefront (and lab test heavily of course).
I'd also schedule like 5 hours for the maintenance window, not 2 or 3. If you get 90% of the way through an have to roll back, you'll need more time. We are doing it in pretty much bang on 2 hours every time (assuming no issues), if you have to roll back (what may involve erasing the box and reinstalling the previous version from scratch) that will take you another 2 hours. Add some checks and stabiliy time either side, it's a 5 to 6 hour window (although assuming there are no problems, 2 hours actual time). Cheers, James. _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
