Backing up and restoring Edge Transport
In the c:\Program files\Microsoft\Exchange Server\Scripts directory there exists a powershell script called ExportEdgeConfig.ps1. You can backup your Edge Transport by executing the following command
From Exchange management shell
./ExportEdgeConfig -cloneConfigData:”c:\CloneConfigData.xml”
To restore:
./importedgeconfig -CloneConfigData:”C:\CloneConfigData.xml’ -IsImport $false -CloneConfigAnswer:”C:\CloneConfigAnswer.xml”
This will create a CloneConfigAnswer.xml file. If everything was correct it will be blank if not you will have to modify it and import it.
./importedgeconfig -CloneConfigData:”c:CloneConfigData.xml” -IsImport $true -CloneConfigAnswer:”c:\cloneConfigAnswer.xml”
