Increase Disk Size Replicated VM

Currently using vCenter 5.0 VM Replication and SRM. I'm looking to increase the disk size on a replicated VM. When doing it I get the following error:

Reconfigure virtual machine:Invalid or unsupported virtual machine configuration.

See the error stack for details on the cause of this problem.
Error Stack
vSphere Replication does not support changing the length of a replicated disk.

Am I right in saying that this means I have to delete the replication, increase the disk size then recreate the Replication? Or is there an easier way of doing it?

Thanks
