Export IIS7 Config
TWEB is the Destination web server.
SWEB is the Source web server.
First, on TWEB make a backup copy of the files in C:\Windows\System32\inetsrv\config. I just created a subfolder called “bak” and copied them. This is very important. If you forget or skip this step because backups are for sissies, you will be re-installing IIS7 in step 4.
Second, copy the AppliationHost.config from SWEB into the C:\Windows\System32\inetsrv\config folder on TWEB. Also copy any application files like your c:\websites folder or whatever over to TWEB in the appropriate location if you haven’t already.
Third, on TWEB open both the new ApplicationHost.config and the backup ApplicationHost.config from step 1 and locate the <configProtectedData> node in the backup. Copy that node and replace it into the new config file.
Fourth, if you didn’t backup the existing config file, remove the IIS role and add it back, then start at step 1.
