I need to transfer live VM's from an old MD3800 to a new ME4024 is there any help out there.

I have a live system with multiple VM servers running on a Dell MD3800 SAN using iSCSI connections, the 3800 is to be replaced with an ME4024 using iSCSI connections.

Can I connect both SANS to the same network Switch and move the VM storage from the 3800 to the 4024.

The VM's can be shutdown for a short period of time while being moved.

Is there any documentation for this type of process.

with thanks

Hello Steve,

There is no documentation for a data migration.  What you will want to do is to have the ME4 and the MD3 on separate VLANs.  They can be connected to the same switch.  You will want to follow the deployment guide for ME4 as well as the best practice guide for VMware.  Here are the links to those guides.

once the volumes are presented to each host, you can move things around at the datastore / VMWare OS level.

vSphere, Hyper-V or something else.

When speaking about vSphere. When using the swISCSI within ESXi the MD3 is configurred without Binding. You must configure ME4 in the same way. For sure you can use a different Subnet or just pick up some free IPs. But i never work with a ME so i dont know if its a Storage which have all ports within one subnet or different ones. The ESXi can only support one (Binding or non binding type) at the same time.

So yes you can connect the ME to the same pSwitch and present LUNs to the ESXi and create a new Datastore. Than you can use svMotion to migrate all VMs from the old Datastores to the new one. If you have only Essentials licenses you have to shutdown the VMs otherwise you can migrate VM while up and running.

If you have 2 or more Servers around you just need one to connect to the ME4 and the other ones use the old MD3. With enhanced svMotion you can move around from one Host to another. This is the lower from the 3 migrate option within vCenter.
