I am making an assumption that you cannot upgrade the eval VM images.
Was running 6.02 and attempted to go to 6.1
Installing CPPM-x86_64-6.1.0.50820-upgrade.bin ...
Upgrading from image file=CPPM-x86_64-6.1.0.50820-upgrade.bin
Extracting image...
ERROR: Upgrade not supported on this VM image
ERROR - Exception performing upgrade: VM upgrade failed
ERROR - Upgrade failed
Can anyone confirm? I have no issue redownloading 6.1 eval vm and exporting/importing configuration.
