When converting a VHD disk image to a VHDX image, does the host system need enough storage space to store both the VHD and the VHDX while the conversion process is running? i.e. is it like a copy job where it builds the VHDX and then deletes the VHD at the end? We have a drive with 4TB RAID and I'm trying to convert a 2TB VHD and I'm concerned that the server will run out of disk space during the conversion and corrupt the images.
Any advice would be much appreciated!
