Moving DC between Hyper-V nodes

hello,

we have two stand alone hyper-V nodes in production each with six VMs as follow:

HV01 hosts these VMs:

• Primary Domain controller for abc domain
• secondary domain controller for xyz domain
• a couple of application servers

HV02 hosts these VMs:

• secondary domain controller for abc domian
• primary domain controller for xyz domain
• a couple of application servers

Due to hardware maintenance we must move all domain controllers to HV01 then upgrade the hardware on HV02 then again move all domain controllers to HV02 then distribute all domain controllers as it was ,again in near future i have to move all DC to a newly deployed Hyper-V node

my question is how do i safely move virtual domain controllers across hyper-V nodes fast and safe

best
