I have a PMPRO setup which is in HA  which is running on Windows 2003 .The current version of PMPRO running is 8400 .I know already from the system requirements that we will not be able to upgrade it to the latest version of PMPRO as the latest version supports Windows 2008 and above 

Will the backup taken on the my current running version of PMPRO i.e. 8400 running on Windows 2003  be restored to  the new PMPRO setup with  OS as Windows 2012 and the Latest PMPRO installed.

Also what final version of PMPRO is  supported for Windows 2003 .and will  the backup from the final version of PMPRO be restored to the newer version i.e 8700 which we will be installing on Windows 2012
