@shubham.gupta_182020 The word "migrated" is a bit of a concern here:

Migrated data from dse 5.0.7 to 6.7.2 and executed

It is not possible to copy the data from a DSE 5.0 cluster to a DSE 6.7 cluster (if that is indeed what you have done). You will need to go through the upgrade process. See Upgrading DataStax Enterprise for the detailed procedure.

In addition to what tim.steele already said, if you did go through the upgrade process then there is also the possibility that there are other issues with your cluster. But our ability to assist you in a Q&A format is limited so I suggest that you log a ticket with DataStax Support and I will get one of our engineers to assist you. Cheers!

Hi Shubham, if you're seeing "not found" then it looks like you've possibly unloaded the core at some stage. You would need to run dsetool create_core to create the core back into the schema.

Can you tell us more on what you've done since with your upgrade from 5.0.7 to 6.7.2, that might point point us to why the core is no longer created?

Tim
