Thanks for the response.
And just to clarify, if both pools have the Documents folder, when I follow the instructions above the separate Documents folders will combine and not overwrite or anything, correct?
Also, on the old pool F (made up of physical drive E and H), a Video_TS folder's contents is split amongst both drives. When the folders are moved out of the pool and into the new pool, the Video_TS folder contents will appear recombined on the pooled drive?
