what mechanism we can used to transfer the data. for example:- Do I need to open port or any other mechanism like RestAPI..... etc. 

Shall I first transformed the data than send to B or shall I send the Raw Data from A to B and perform the transformation at B. 

Which approach is more reliable in Production and why ?.

Thanks a lot for your help.

If the two workspaces are in the same region (same control plane), then there is no need to transfer data.  Remember, Databricks does not store your data or put it into a proprietary format.  You give Databricks the permissions to access the data that resides in your cloud account.  It is just a matter of granting privileges via Unity Catalog.
