Best Practice for replicating EV drives for USL DR

The scenario is 2 clustered EV servers, EV1 cluster in PROD site, EV2 cluster in DR site.

For failover, customer is replicating index and storage locations.

Question: Do they also need to replicate the following locations from EV1 to EV2?

- msmq

- index metadata

- ev cache

- ev storage queue

- ev temp

The reason I ask is because, even though EV2 has no data of its own (strictly DR), however it has its own locations for the above 5.  Wouldn'r replicating cause corruption on EV2? 

For example, EV1 and EV2 are running their own msmq storage locations.  Replicating EV1's msmq will write over EV2's msmq storage location.  Would't that cause issues for EV2's msmq to start up?

Thanks,
