In previous versions of vCenter Converter you had the option to synchronize a P2V conversion to complete a hot migration. This meant that, after a initial full backup (or P2V) of the source system, a second run was initiated right away to save the last changes to the new virtual machine. Before this second run started, you had the option to stop certain services so the consistency of the disk was guaranteed. After this second run completed, your new VM was ready to go. Any additional changes in source server are not synced anymore, because the P2V process finished.
In Converter Standalone 5 there are two new options available:
- You can schedule this second run and….
- You can choose to perform a final synchronization
Both options are visible in the Converter interface:
The first option is pretty clear I think; now it’s possible to schedule the second run at a selected date/time. The final synchronization option determines if a sync is the final (and last) sync, or maybe you want to schedule one or more additional synchronization tasks between the source server and the destination VM. This means that your P2V’ed VM can stay in sync for a long time. You can start the final synchronization at a moment that is convenient for you. Hmmm, that’s pretty cool I think :).
Let’s see how this looks in vSphere, where I have a VM available that didn’t had a final synchronization:
As you can see, the VM (this is the P2V’ed virtual machine!) has two snapshots. One snapshot was created after the initial transfer, a second snapshot was created after the second synchronization run, although this was not the final synchronization.
So, let’s now go to vCenter Converter: Here I have the option to start an additional synchronization. This job will sync the latest changes from the original physical machine to the virtual machine:
Now the wizard pops-up again, in this case I am selection the final synchronization option:
Because I have selected “final synchronization” the new VM will be ready for use, after the final synchronization. Converter en vSphere will do some magic with snapshots, sync the last changes…and voila…your VM is ready to go!
