The following script will accept a vCenter and two datastores as input, and move VMs from the source to the destination one at a time. The requirement for this script was to perform the migration without babysitting, but to not overwhelm the storage infrastructure by kicking off tons of VMs at once.
Here’s the script – feel free to modify or copy! Load it by running the .ps1 file, then use the Migrate-DS command to perform the migration.
I get tired of waiting for PowerCLI to load and then typing Connect-VIServer over…and over… So I figured I’d do something about it. When I launch PowerCLI, I now get a pretty little menu that allows me to pick which vCenter server I want to connect to.
I was looking to find all the VMFS3 datastores still existing in an environment today so that we could migrate them to their new VMFS5 counterparts. I used this PowerCLI one-liner which I thought someone else might find useful. Let me know if it helps!

Often the storage offload capabilities of a storage array (VAAI in vSphere terms) need additional software to integrate with ESXi. This post will walk you through installing the NetApp plugin required to leverage VAAI on an NFS datastore. Good luck!
Sometimes it will be necessary to uninstall a third-party driver that has been installed on an ESXi host. This is a simple process; however, it does require the host to be rebooted. Allow me to guide you through this process.
