This is how I've done it a few times and it seems to have done the trick although I do realize this is not a "full" back up and restore, but it covers off the majority of what's important:
1. Use VM Pro Client to back up the data base (.mdb file) to my PC
2. Go into the Windows server - Program Files (x86) - Avaya - IP Office - VoiceMail Pro - VM - and copy the audio files in the Greetings, WAVS and Names folders to my PC in folders of the same name to keep things straight
3. Access the Linux command line on the App Server to change the write permissions of the Greetings, WAVS and Names folders - /opt/vmpro vmpro]# chmod 777 for each of the 3 folders
4. Use WINScP to copy the .wav files that were copied in Step 2 into the appropriate folders on the App Server. The Greetings, WAVS, and Names folders are write protected so Step 3 is necessary to allow Step 4 to work.
5. Use VM Pro Client to restore the .mdb file to the App Server
6. Give the App Server the same IP address as the Windows server or adjust the VM Pro address in Manager accordingly.
VM to Email settings will still have to manually configured on the App Server, and if you have a more advanced VM Pro with Group announcements, campaigns etc., there will be more work to do than what I have laid out above, but for the majority of our customers this has sufficed.
