My (retired) Laptop XP (with VMS plat 7) has been replaced with a Desktop (Vista32). I would like to upgrade (purchase) to the VMS platinum pro 9 from this site. Do I need my previous version installed or does the upgrade take care of everything I need to get started (again)?
The check if you can upgrade is made at the purchase time.
When you get/download the "upgrade" (in fact a normal version) you have received the new serial number - and this is all that you need on the new machine.
