esxi 5 removing luns from datastore

We have an esxi5 host which has luns presented from an old storage array. These luns (devices) are in a datastore (hope im using the correct term).

The datastore contains multiple VM's on the esxi host.

We recently started having problems with the storage array, so I created 4Tb of new luns, presented them to the esxi host and added them to the existing datastore.

The intent is to move (pvmove or other) the data from the old luns to the new luns and then drop the old luns from the datastore.

However, I can't seem to find the equilivant command to pvmove to move the data from the old luns to the new luns in the same datastore, and I don't see any menu options in vsphere to remove the old luns from the datastore either.

Suggestions or advice is welcome.

Data can be moved using datastore browser.  To do that, Click on any host, navigate to configurations tab.

Hardware Pane > Storage >  Select the datastore, right click > Browse datastore. Now datastore browser opens.

Select the items that you want to move to another datastore, and once selected all, you can see on the top a button to move all the data as shown in the pic below.

For removing LUNS / deleting the datastore please look into the KB article.

The difference is that I need to move the data from one lun to another in the same datastore, not between different datastores.

I have already added the 4Tb of new storage to the existing datastore and need to move the data from the old luns to the new luns.

If that cannot be done, then I need a way to remove the 4Tb of new luns from the old datastore so I can add it to a new datastore.
