Hi all,

When trying to execute the Cassandra cluster migrator tool, it remains preparing the agents for migration, looking at the SLCCMigrator.txt found some errors about it Could not ping agent

2022-06-08T14:35:51.240|WARN |DataGateway.Migration.CC|Could not ping agent 22104 @ WIN-F9JBKVOMUHS. Retrying soon... Exception: Skyline.DataMiner.MessageBroker.Exceptions.RequestResponseTimeoutException: No responders are available for the request.

It's a 2 DMA's cluster, both of them are online and running Dataminer 10.2 CU3

From the troubleshooting section of the guide Cassandra Cluster Migrator - DataMiner Dojo, we tested on both agents and the cluster tag is empty

"cluster": {}

Using the Client test tool, we sent a NatsCustodianResetNatsRequest, tried to execute the SLCCMigrator tool again but nothing changes.

Both agents have the same config in the SLCloud.xml

SLMessageBroker_SLCCMigrator.txt log file always show the same messages.

Any idea what else could be checked to successfully execute the migration?
