Currently on GW 6.5 SP7, upgrading to GW7 soon.

We have a remote office connected to our main site using a permanent VPN tunnel. We're looking to place a remote server over there to increase their performance by giving them a local PO and library as we also make extensive use of DMS.

Is there any way to have a 'mirror' of a DMS so that the remote office can modify the files against their library and then the updates are copied back to the master library by the server later?

The real aim is to get the remote site to have quicker access to our docs and both sites need shared access to all the documents at a quicker speed than the VPN can allow data to move across it.
