When you head into the Federated Monitoring page (i.e. Administration -> Monitoring -> Federation Status) you may see that one of the JPDs have N/A in all of its columns.
This can mean that there is an issue with reach that other jpd or that there is some migration taking place and as a result the information is not available. We will be covering on the latter situation when a JPD is reporting that "Monitoring is unavailable, migration in progress".
In this article we will first confirm that the issue encountered is from the unfinished migration. Then we will confirm that the migration is unfinished. Finally we will demonstrate a potential remedy.
