Finally looking to update my environment to a newer version (currently on 7.7).  We are still running a security server and wanted to find out a few things before the upgrade.  I am waiting for a hardware upgrade for one server but was hoping to get things started on this upgrade as soon as i can.  Is it a good idea to replace the security server with a UAG?  If so, are there any suggestions about do's and Don'ts?  I am looking to take my environment up to at least 7.12 for now.  Haven't had time to investigate version 8 yet so not sure i want to go there. For now I am curious about replacing the security server.  Any thoughts or comments would be appreciated.  Thanks.
