VSS snapshot timeout - anyway to increase from 5 minutes

We are using vmware converter to migrate a VM from Azure. The migration is running until the synchronisation task when VSS snapshots of the volumes are requested. The converter attempts to snapshot all the volumes, waits five minutes and then requests snapshots of the volumes individually. It then immediately fails.

VSS snapshot failed: Unable to create a snapshot for volume \\.\Volume{ab77851f-a0df-11e6-80b4-806e6f6e6963}. Error code 259 (0x00000103)

I suspect the VM is still trying to complete the initially requested VSS snapshots. I manually ran the command

vssadmin create shadow for=e:
and it took 9 minutes to complete.

Therefore is there anyway to increase the initial 5 minute timeout value that the converter uses.

Thanks in advance for any assistance.

Unfortunately there is no way to do that, so before running the V2V try to free some resources on the VM and if you have some VSS snapshots try to delete them.

Something else I recommend you is to stop the application that is running inside before starting the migration as it will also prevent corruption during the process.
