Need a PowerCLi script to move a host to a new cluster

Yeah so, not much point doing this.

Drop the server into maintenance mode, let them trail off naturally.

Disconnect the server from the cluster, reconnect on the other side.

You cannot move both the host + the VM's to a new cluster without V-motioning them off.

You sure? what if DRS will be turned off?.  I need the vm's to stay on the host.  Thats why they will be shutdown first.

I need to script this so i can set it to run at a certain time so i don't have to do it manually.  I figured this would be simple enough to understand

You're missing the point here, the VM's are attached to the current cluster, you've actually contradicted yourself in your main question

1.)gracefully shutdown all guest vm's running on a single host

2.)Disconnect the host from the cluster its currently on

Is it a single host or a cluster?

its currently in a cluster as of right now.

if i have to vmotion them off then i guess i have no choice.  Guest VMs will be powered off so there should be no resource contention issues.

Just drop the host into maintenance mode, then V-Motion the other VM's to the new cluster, it's the easiest way.

I mean you could script the v-motion, but you're better off doing them during the day

I'm confused, assuming both clusters can see the storage, there's nothing to stop you adding this host to the new cluster without powering off its guest VMs? Ive done this on many projects in the past, in fact when you add it to the new cluster it asks you to confirm adding all the running VMS to the new cluster? obviously port groups and VLANs also need to match.

This is generally how I replace all the hosts when creating a new cluster on new hardware. (In fact I've got a client that moves servers from Pre Prod to Production using this method (which is convoluted I'll grant you, but that's what they want :) )

If you think about it remove a host from a cluster and add it back to the SAME cluster nothing happens, we used to do this when the HA agent got its knickers in a twist, we didn't down the guests or put the hosts in maint mode. join the host to another cluster is basically the same thing, with the need to sort the licences out afterwards?

The purpose for this is i need to move these hosts to an EVC Enabled Cluster.  The VM's are currently using the instruction sets of a CPU family that is higher than what the EVC Enabled Cluster is set to.  Therefore, vm's will have to be powered off.  Are you implying that i can move the host from its current cluster to the EVC Enabled one without powering off the VM's?
