steps to change IPs for primary and DR storage after configuring the replication

Hello,

   I am new with Dell EqualLogic. we are implementing a DR solution with Dell Equallogic storage replication and VMware SRM 5.0.1.

We have finished the initial replication and started the schedule for LUN replication.

Now customer want to change the primary and DR storage IP subnet from 172.x.x.x to 10.x.x.x. we know that this decision should be taken during design phase but unfortunately customer :emotion-16:...you knows...:emotion-6:

is there any way to change all the IPs for Source(primary site) and Destination(DR site) storage, without affecting the replication?

NOTE: write now both storage boxes are at primary site(source site).

Appreciate any suggestions..

Thanks
