[cisco-voip] Cucm 8.0 to 9.1 upgrade - UCSS Query

[GR]

Anyone did upgade to CUCM9 from 8.X? I am pretty much sure with active UCSS we get major version upgrades free - can someone confirm?? Just wanted to get an estimate if therez any cost involved from licensing point of view when moving to cucm9?

Also any gotchas I need to be aware of?

Thanks.
