Migrating from MSA 2012sa to MSA 2042, data copying question

[YannickG]

Hi,

I have a pretty basic setup with two ESXi servers connected to the MSA 2012sa by SAS and we are getting ready to migrate to an MSA 2042 connected by FC.

The 2012 SAN has two volumes, one for storing VMs and another one for enterprise files. I only have a vSphere Essentials licence, so no vMotion.

What would be the best and fastest way to copy all my data to the new SAN.

Downtime is possible during the week-ends but if I could do some steps during production time, that would be a big plus.

Right now my plan was to connect the new SAN to both ESXi servers and use vCenter to shutdown then migrate the VMs (storage only) to the new SAN.

Is there a better way without getting vMotion? Maybe some HP SAN tool I don't know about.

Thanks
