I'm working with four datastores, each providing 20TB for a total of 80TB. I'm looking to rearrange the allocation to something more like 50-10-10-10. Can this be done within vCenter, especially since there are various VMs currently hosted on these datastores? Any guidance would be appreciated!

You'll likely have to create four new volumes on your storage and then create four corresponding datastores in vCenter. To migrate the VMs to these new datastores, you'd need to use storage vMotion. For your plan, you'd expand the first datastore to 50TB, while the other three should be migrated to new 10TB datastores.
Datastores are essentially partitions on a LUN, so you'd need to consider your storage capabilities. It seems unlikely that you can do this without manually transferring the VMs and recreating the volumes. It ultimately depends on your storage setup.
Would that mean I'd need to purchase an additional 80TB of new storage for this to work?
