Added to the Auto FE Updater FAQ
Q: I'm moving the files from one server to another server. How do I easily use the Auto FE Updater to get the users to use the FE from a folder on the new server?
Q: I want to move the BE MDB to a different folder on the same server.
There are two parts to this. One is to replace the FE MDE so it's linked to the new server path and folder structure and the other to change the target of the shortcut to use the new Auto FE Updater INI file.
On the day of the switchover delete/rename the BE MDB file from the old server so just in case something gets missed they can't work with the old MDB file. You're moving it to a new server anyhow so don't leave it easily available on the old server.
Copy the new FE MDE which is linked to the new BE server and folder to the FE path on the old server. This way when the users run the old shortcut for the first time they will get switched over to the new FE MDE.
Update the AutoFEUpdater INI file on the old server to be the same as the INI file on the new server. When the users run the new INI for the first time they will get a warning message saying the shortcut on their system is different. Use the ShortcutErrorMessageHandling=2 option on the INI file on the old server to ignore that message so the shortcut gets updated transparently.
This can all be tested ahead of time.
