Migrating Hyper-V VDI machines

Hello! VDI/Hyper-V noob here. I have a VDI deployment with a bunch of Hyper-V VMs spread across 2 physical servers and I need to combine this all onto one server. What is the process to safely take all my VMs on server 2 and migrate them to server 1?

OS is windows server 2016, VMs are running Win10 Enterprise. VDI is a persistent pooled desktop collection.

Thank you for any help you can offer! I know this may be basic stuff but I'm trying to learn a ton as I go.
