Syntergy Replicator Overview (Now Metalogix Replicator)
The Syntergy replicator provides inter-farm replication services for MOSS 2007 and WWW v3.0. The installation and configuration manuals are well written and provide you with screen shots so you know where to find things and have a sense of context no matter what step you’re in during setup. The user interface matches SharePoints look and feel to help reduce the learning curve of administrators. Assuming you have both farms within your grasp, you should be able to setup and configure simple replication within an hour - of course this doesn't include change control and having recent full backups before doing anything to a production system.
