Zerto live failover with VMs shutdown prior.

Hi All,

I want to do the following.

Shudown VMs on protected site.

Perform Live failover. (Commit option. None, VM Shutdown. No, Use latest checkpoint)

Perform OS health / networks tests in DR site (<24 hrs)

Select Rollback

Manually restart Protected site

Want to know if:

After manually shutting down VMs will a checkpoint be written automatically?

If not can I create a checkpoint on the VPG?

Will ZVRAs continue to detect IOs and replicate any change until I commit/rollback?

If I select to rollback will VMs in recovery site be shutdown and unregistered. (expect yes)?
