You can change licensing without a reboot.
I'd add it to a VC if I could, but if you do not have a VC, you simply need to shut the VMs, remove them from inventory, copy them to the new storage (if they are not on network storage) - then import them on the new host.
alternatively, you could try automate it:
If you need something to copy the VMs, I'd consider trying FastSCP by Veeamm.
the other alternative is to use VMWare convertor . . . but I always favour moving the files personally.
One day I will virtualise myself . . .
