About synchronization status when using Bulk migration

[yokoth]

When doing virtual machine migration with HCX Bulk Migration, is the final delta synchronization done after the source virtual machine is shut down?

[yokoth]

There is another point to worry about.Is there a way to confirm the start and completion of delta synchronization?

Bulk will do an initial replication which uses HBR under the hood. Once the initial synchronisation has occurred it will maintain a 2 hour RPO on that sync. When you initiate the migration switchover, HCX will power off the VM and then it will do a final cold synchronisation prior to cutover.

Stats wise you can follow the following KB:

https://kb.vmware.com/s/article/2081078

Use this to get all VMs and map the VM ID to the one being replicated:

vim-cmd vmsvc/getallvms

Then use this against the vmid of the VM you are interested in to see stats.

vim-cmd hbrsvc/vmreplica.getState vmid
