Upgrade from VM Workstation Player 5 to 15.5

Hi all,

I have a couple of Windows 7 Pro guest machines installed with VM Player 5.0.2 in  in Windows 8.1 host many years ago, I am planing to upgrade to VM workstation player the latest version 15.5 in Windows 10 Home Host.  My questions are,

1. Can I simply copy old Windows 7 guest machines (VM Player 5 in Win 8.1) over to the new environment (VM Player 15.5 in Win 10) and start the guest machine without any issue?

2. Do I need to change any configurations in the old guest machine to meet any requirements or optimize its performance?

I am looking for a hassle free and seamless upgrade.

Thanks for you time and input.

James
