Hyper-V 2012 manual live merging?

Hello,
I have a Hyper-V 2012 server and a guest with a giant AVHDX (300GB).  I deleted the snapshots when I discovered them and it started to do a live merge.  However, at the time I didn't think I had the disk space to complete it so I cancelled the merge.  Now that I've cleared up space, it looks like the only way to merge the diffs is to turn off the guest and wait.  This guest can't take the kind of downtime a 300GB merge would require and when I turn the guest back on, it seems to cancel the merge.  Is there a way to manually kick off a live merge again?

Thank you in advanced.

I don't believe it is possible. There are some VSS things that are required for a live merge to work and when you cancelled the merge, they went away. My understanding is that there is not a supported path ot reconstitute that particular metadata.

OK.  So a related question, can I turn the server off for a little while everyday and let the dif catch up a bit or does it start over every time?  It looks like it picks up where it leaves off, but I'm only judging by file sizes so it's not definitive.

I don't think that'll work.
