Hyper-V Replication network related questions

Hi Members,

I enabled Hyper-V Replication from Hyper-V Cluster (Primary Site at 10.11.x.x) to Hyper-V Standalone (DR Site at 10.1.x.x) all required settings successfully configured like Hyper-V Replica Broker ,AD Object and others.

I Tested Replication works fine and replication is healthy.

I have some machine like ORACLE ERP which are web based like users type http://erp.abcd.com for this we enter A record 10.11.0.35

now what happend when we want to do planned  failover for above machine 

should i assigned another IP for replicated machine and then change my A record for DR IP ?

or 10.11.0.35 still works for replicated machine ?
