If you re a messaging administrator or consultant working for a relatively large organization, deploying one Edge Transport server in the parameter network (DMZ or screened subnet) might not be sufficient. So your big question might be whether it s possible to deploy multiple Exchange 2007 Edge Transport servers, and if it is, how is the data in the ADAM store replicated between each Edge Transport server? Luckily you can answer yes to both of these questions; this section explains how to do exactly that.

You can deploy additional Edge Transport servers in your organization by cloning the configuration from the server that has already been deployed in the perimeter network. This is done by copying and exporting the configuration from an existing Edge Transport server (source server) to an XML file using the ExportEdgeConfig.ps1 script, which can be found in the Scripts directory under C:\Program Files\Microsoft\Exchange.

The ExportEdgeConfig.ps1 script exports all user-configured settings as well as data (except the EdgeSync subscription settings and the certificates that are used by the Microsoft Exchange EdgeSync service) to the XML file.

The configuration then needs to be copied and imported from the XML file to the newly installed Edge Transport server (target server), which is done using the ImportEdgeConfig.ps1, also found in the Scripts directory.

When you import the XML file on a new Edge Transport server using the ImportEdgeConfig.ps1, the script checks whether the configuration information and data exported from the source...
