I run the migration manager and after I pick the ip addresses it runs for a while and then ends and gives me the following error message: Error: Unable to deploy the migrated objects: Unable to run migrmng: Empty error message from utility. I have checked the log file and it looks like it goes through everything. It definitely has a connection to the source server. Could this be a possibility that it cannot copy data because a port is not open? I opened port 6483 on the destination server. What could be the cause?
