Migrate CosmosDB Cassandra from CC to GCC

Elango Thiagarajan (NCS) 21

Hi Folks,

I have a scenario where I need to migrate Azure CosmosDB Cassandra DB from the Commercial Cloud to the Government Cloud. Is there an easiest way to do it?

I don't find any document describing how to move Cassandra from one platform to another.

Is moving the entire resource directory between two subscriptions possible?

Any pointers will be helpful.

Hi Shakthi,

CQLSH is recommended only for small dataset right? our database is quite big close to 1TB.

Alternatively we are looking for migrating to MongoDB
