Rules Upgrade - Failed with NoClassDefError - DirectStreamEnvironmentAdapter

As part of Upgrade process, we are upgrading from PRPC6.1 to PRPC 7.2.2, we ran the migrate rules and this was successful. Our current 6.1 environment, system name has been updated to "Pega_DEV4_ENV". We updated the file with the current system name, that is changed "pega" (that is default in media file properties) to "Pega_DEV4_ENV". Now we ran the upgrade, the upgrade is failing with error:

NoClassDefFoundError - error. I did some research for this issue on PDN and found following links:


This says this might be a bun and could be fixed with next ML release.

This says update the system name to fix this issue. I wanted to confirm what the system name should be when I run the rules upgrade. Should it be current system name for PRPC 6.1 environment (Pega_DEV4_ENV) or should remain "pega" which comes OOTB with the media file.

My understanding was that we need to update system name to "Pega_DEV4_ENV".
