Yes Jeff, want to achieve the same ( *You’re trying to go local quorum in
one dc to local quorum in the other dc without losing any writes*)
Thanks for your quick response.

You’re trying to go local quorum in one dc to local quorum in the other dc
without losing any writes?
The easiest way to do this strictly correctly is to take the latency hit and do
quorum while you run repair, then you can switch to local quorum on the other
side.
A few more notes inline
While switching over datacenters, there is a chance of mutation drop
because of which inconsistency may occur.
To avoid inconsistency we can do following :
Monitor and if require then run repair
1. Monitor tpstats in all nodes. If dropped message count is 0, it
can be inferred no mutation
