After upgrade to 10.2.1, I receive following Error in the alarm console: Could not initialize SQL to CC migration request handler.
Can you please inform what's the impact of this Error? And how to resolve it? Thanks.

This error indicates that it will not be possible to initialize a migration connection, something that is needed to migrate from SQL/Cassandra to Cassandra Cluster. Other than this feature I do not believe anything else is impacted.
In my experience these are often a result of an issue in the NATS cluster on the DMS, so I'd recommend to check the SLMessageBroker.Crash logging to check if something went wrong there.
Does the alarm contain a stack trace? I have seen this error when there are NATS problems on the DMS, I would check if SLMessageBroker.txt (or SLMessageBroker.crash.txt) contains more info.
