There are two ways I've gotten around this issue:

1. Add replicas in the target data center after CDCR bootstrapping has 


2. After the bootstrapping has completed, restart the replica nodes one-at-time 
in the target data center (restart, wait for replica to catch up, then restart 
the next).

I recommend doing method #1 over #2 if you can. If you accidentally restart the 
leader node using method #2, it will promote an out-of-sync replica to the 
leader and all followers will receive that out-of-date index.

I also recommend pausing indexing if you can while you let the target replicas 
catch up. I have run into issues where the replicas will not catch up if the 
leader has a fair amount of updates to replay from the source.
