Migrating Protection group to new storage pool

Question

Hello all running DPM 2012. The environment was setup prior to my arrival and it was setup with 10 1.5TB storage pools.  I heard the thinking was this was the recommended size for storage pools.  Problem is now we are/have run out of disk space
on those storage pools and jobs are failing with "DPM does not have sufficient storage space available on the recovery point volume to create new recovery points (ID 214)"
I have created new 4 new storage pools of 10TB each and I want to know how I can migrate the protection group data to the new storage pools and have the protection group use the new storage pool moving forward.  I want to empty the smaller storage pools
so I can kill them off and create larger storage pools.
Unfortunately the GUI does not allow me to point to specific storage pools, it should, and I'm not familiar with DPM Shell commands.
Any suggestions would be appreciated.

Hi,

The following commands can be used with the ntdisk number as seen in either the get-DPMDISK output, the Windows Disk Management GUI or DPM Management - Disks GUI.  In my example disk-0 is the system/boot disk and not used by DPM storage pool.
EXAMPLE These commands show the migrations going from NTDisk 1,2,3,4,5,6,7,8,9,10 to NTDisks 11,12,13,14 
$source = get-dpmdisk -dpmserver DPM-SVR-NAME | where {1,2,3,4,5,6,7,8,9,10 -contains $_.ntdiskid}
$source
$destination = get-dpmdisk -dpmserver DPM-SVR-NAME | where {11,12,13,14  -contains $_.ntdiskid}
$destination
Once you are satisfied the outputs are what you want, then run the following to do the migration:
MigrateDatasourceDataFromDPM.ps1 -DPMServername DPM-SVR-NAME -source $source -destination $destination
