Additional Information
The issue found to occur on XIO and Unity arrays. It appears to be related to Windows 2019. Not able to reproduce the issue on Windows 2016.
If the host crashed in targetselected state, then after the reboot migration state reached commited , at this stage we are able to copy the files from SAN disk to the source migration disk without any crash.
Howver when we reach committed through sequence of events like setup -> sync -> sourceselected -> targetselected -> commited (without copying any files in these stages) and then if we copy files from a SAN disk to the source disk at commited state, the host crashes.
