[jamal1]

using retina mid 2012 macbook pro 8 ram, os x 10.9.5 with parallels 10 and windows 7, 32 bit - everything is perfect. but now im thinking to upgrade to catalina 10.15.4 and then buy parallels 15, will my windows 7 32bit work fine? do i need to reinstall windows 7? do i need to backup?

Hi jamal1. You can use the same Windows 7 virtual machine after upgrading to macOS Catalina and Parallels Desktop 15 for Mac. However, take a backup of the virtual machine to an external hard drive before doing the upgrade.
