Migration of Windows 32-bit to 64-bit

I realize now that I should have installed the 64-bit version of Parallels along with Windows 10. I've been using it for awhile so I have various apps installed, including Office 365. I know I have to create an new Parallels VM. Is there a way to migrate the contents of the existing VM to the new one? Or is it going to be a full installation slog?
Thx

 

Hello, you can add your hard drive as a second hard drive on your new VM.
