Currently on UM 4.2 (no failover) and plan to upgrade because we also are upgrading to Exchange 2007 with clustering.


Wonder what folks feel about Unity 7. I prefer 5 cause it's been around longer so believe it is more stable.


what were pros/cons with other folks?

Unity 7 is basically Unity 5 except a few more features. You will not have a problem there.


the issue is that I think Exchange 2007 clustering is not supported yet but will be in the future.

Capacity is the biggest factor for us. Unity 5 supports up to 7500 users and 144 ports. Unity 7 is 15000 Users and 200 ports. Unfortunately Unity 7 does not work with Exchange 2007 using CCR (continuous cluster replication) so we have to go with 5 for now and set up an additional server to handle capacity (over 11000 users) until its fixed in 7 (or 8 or whatever version it works with).
