Environment

VMware vRealize Automation 7.5.x

Cause

This issue occurs due to an issue with the command framework that the migration uses in vRealize Automation 7.5.x and 7.6 when the virtual appliance timezone is different than UTC.

Resolution

This is a known issue affecting upgrades to VMware vRealize Automation 7.5.x or 7.6.

Currently, there is no resolution.

Workaround:
To work around this issue, set the virtual appliance timezone to UTC prior to the migration.
