in place migration for a host server with RODC VM

Dear experts,

we have a windows server 2008 R2 SP1 running a host for a hyper-V, one attached VM is running a RODC that is synced with our global AD in the head office, the RODC is running the same OS (windows 2008 R2 SP1).

I plan to migrate the host to windows server 2012 R2 and keep the virtual machine running the RODC as it is (same OS =win 2008).

Q1: if the in place migration to windows 2012 r2 was successful would the RODC start up normally without issues?

Q2: if the migration failed and I wanted to rollback using a full windows backup that includes system state (bare metal restore), would the RODC start normally? is this a good roll back plan?

Q3: Can we move the RODC VM by copying all the VHDX files along with all other configuration files then attach it to another host maintaining the same IP? would that affect the RODC?

Q4: what is the best action plan to perform this migration safely?

Your best action plan is to have a second Host where you would migrate the RODC off of the Host you want to upgrade and then when the Host has been successfully upgraded you can then move it back.
