Re: How to migrate a powered off VM from a DataStore to another

Hi,

If you are using vSphere 5.X, then you can use SDRS , storage DRS, which automatically trigger storage migration of VM based on I/O load and storage space availability on datastore.

"vSphere Storage DRS continuously monitors storage space and I/O utilization across a pre-assigned pool of datastores and intelligently aligns storage resources to meet your business growth objectives."

Here is  blog from VMware on SDRS
