VPLEX Metro Data center relocation without full rebuild?

Hello,

I have a question for the VPLEX Gurus?

We have a VPLEX VS2 Metro deployed with one cluster in data center DC1 and another in DC2.

Most servers are ESX in uniform host-access cluster setup (Each ESX is cross connected to both VPLEX clusters).

Later this year the customer will mover from DC1 to another data center DC3.

Move virtual server load to DC2.

Shutdown hardware in DC1 and move it to DC3.

Connect and power-up hardware in DC3.

But how can we make sure that the VPLEX Metro will not do FULL rebuild?

We already did a basic test: unplug all BE FC cables between the VPLEX in DC1 and the Storage Arrays in order to simulate bringing down the Storage.

But after replugging we had a FULL rebuild.

Thanks for any experiences or hints,

Francis
