You need to get a copy of the VMPro installation for the release that matches the 412. Probably have to use compatibility mode to install. Once that is done, AND the VMPro has connected to the IPO, copy the Accounts, Names, Greetings, and WAVS folders, overwriting what the new installation and connection to the IPO creates. Restart the VMPro service to have it see the new account folders and index the messages. Find the .mdb file that has the modules and import it, then save and make live. If you can't find that you will have to recreate the automated attendants and other modules as best you can with the customer's input on how it supposedly worked before.
