Before deleting the entire content of the old Platform Server installation folder, backup the following files, so you don't need to reconfigure the Platform Server again:
The Server.hsconf file will hold the entire Configuration Tool settings, and the *.exe.config files will have any customization to the OutSystems services and Compiler.
If you backup the server.hsconf file and restore it onto the new installation directory location, when you run the Configuration Tool again it will automatically load the settings, so you don't need to setup the database server/catalog/users, nor the service specific settings again.

Only you to come up with a hack like this! Great show!
This is indeed a safe way to change the Platform Installation directory without having to reinstall it.
Not really sure what happen with your forum post, but it's ok now!
