Thanks Anuj. In our setup it's already NetworkTopology for system_auth. Not sure if it was default or whether we altered it at some point. Repair seems to take forever. A few things that worked for me:
I used cqlsh to connect to one of the nodes in existing DCs and set consistency to ALL. After that I changed the password of the user I wanted to connect to. Voila :) the consistency worked and I can now connect to the new DCs using the user. I guess if I do it for all users, it will work. This is enough for me. However, I would think 'nodetool rebuild' and a restart should take care of this. Not sure why it doesn't.
