Hi there, we have many WRAP 2c Boards running our wireless towers, Upgrading is as simple as upgrading a WAR board or PC. HOWEVER... we have had touble in the past if upgrading more than 3 minor releases, eg.. currently 2.9.24 upgrade to 2.9.27 or 2.9.11 upgrade to 2.9.14 etc. And if you have 400mw cards it will forget your interface configureations for you after the reboot that follows upgrade. Although access lists, firelwall rules etc usually stay intact.
Just my 2 cents.
Keep tryin' its bound to work!!
