I was involved in a vRealize Automaton 7.x migration project, we did encounter failure at a point where we were trying to backup vRA license.
Let me share some snippets

So one can see above the task of backing up license was a failure.
Let's understand what happens at this point in time. When a backup of license script is triggered we execute a command called
[master] sevenvra:~ # /usr/sbin/vcac-config license-info
---BEGIN---
[{"licenseInfo":{"@type":"SerialKeyLicenseInfo","serialKeys":["YYYYYY-YYYYYY-YYYYYY-YYYYYYY"],"expiration":null,"restrictions":[{"product":{"name":"VMware vRealize Automation Enterprise","editionKey":"vac.enterprise.serverVm","suiteName":null,"family":{"name":"VMware vCloud Automation Center","version":"7.0"},"id":"VMware vCloud Automation Center7.0vac.enterprise.serverVmserverVm"},"costUnitLimits":[{"enforcementType":"hardEnforced","unit":{"id":"serverVm"},"value":25}],"licenseProductCapabilities":[{"version":"7.5.0.0","features":[{"id":"vac"},{"id":"vdc"}],"keyValues":null}]}],"name":"vRA Standalone License"},"id":"urn:vri:com.vmware.license.license:XXXXXX-XXXXXX-XXXXXXX-XXXXXXX-XXXXXXX","assetId":"urn:vri:com.vmware.license.asset:comvmwarevcacstandalone"}]
---END---The output of the above command returns serial keys and other parameters required which would be applied to the destination server where we are migrating data to.
If we read the exception, there is some sort of corruption happening when the values are being returned by the command.
The path or remediation plan implemented was to remove the existing license on the Source vRealize Automation server and then re-implement the license after we reboot the server.
Steps to remove license on a vRealize Automation 7.x node have been documented in my previous blog article. Click on this link and read the procedure.
Once the license was removed and re-applied give a shot at migration and it should work.
