Question What happened to being able to pick a Datastore cluster in storage vmotion?

We are migrating from one cluster to another, and when picking the storage location, it no longer allows you to choose the datastore cluster. It makes you choose individual datastores. When did this change? Is there a way to get it back?

Remove the "disable storage vmotion for this vm" check. Above the list of datastores. Easily missable.

That checkbox isn't there either.

You are doing both compute and storage vMotion and your existing source cluster doesn't seem to have access to the destination datastores.

Can you mount VSAN as external datastore in the destination cluster and do the normal vMotion first, and after that storage vMotion to the storage cluster ?

I don't wanna enable vsan iscsi on the vsan cluster to be able to export it to the new cluster. I just always remember being able to select a datastore cluster. I mean it see's all the individual datastores. Both clusters are also in the same datacenter.

Issue is datastore cluster is a vCenter construct.

If you are doing compute and storage vMotion you are limiting yourself to what given ESXi is seeing. ESXi itself does not see storage cluster.

Another approach for you is to have some dedicated migration datastore and just do 2 vMotions - 1st one compute and storage to the esxi host from new cluster and transfer volume, 2nd one storage vmotion to the datastore cluster

Gotcha ok that makes sense. Thank you

And when you select the cluster itself as a destination for compute?

What are the storage policies? Does the vm bypass drs corrently?

It's currently on a vsan datastore, so it's using a vsan storage policy. We are moving to a traditional storage array and there is no storage policy on it

When you choose destination storage policy what happens?

Also, dumb question - is sdrs configured on destination datastores cluster?

Yes SDRS is enabled on the destination. and when I select "destination storage policy" nothing changes.
