I'm trying to upgrade a Vcenter 5.5 appliance to 6.5.
I get the following error:
"Unable to retrieve the migration assistant extension on source vCenter Server. Make sure migration assistant is running on the VUM server."
Log file says:
2018-04-04T15:07:58.074Z - info: VUM upgrade switch enabled, query extensions and get the size info
2018-04-04T15:07:58.109Z - info: Got the extension: com.vmware.vcIntegrity
2018-04-04T15:07:58.233Z - info: MA extension not found
2018-04-04T15:07:58.234Z - error: There is no MA extension for VUM available on source VC.
I've been searching for this error and every article I've found says mount the iso on the vcenter source sever and run vmware-migration-assistant.exe. But my source vcenter server is the linux based appliance so I'm stuck on what I should do?
