https://community.netapp.com/t5/ONTAP-Hardware/Convert-2240-4-to-Disk-Shelf/m-p/105155#M6519 <P>My company purchased a FAS2552 with SSD to add a Flash Pool to our current setup. Currently we have a FAS2240-4 with&nbsp;24 x 3TB drives in 7-mode. The plan is to convert the FAS2440-4 to a disk shelf and have the FAS2552 act as the controllers. My question is, do I need to transition&nbsp;the FAS2240-4 to CDOT before &nbsp;I convert it to a shelf? The FAS2552 is already running CDOT 8.3.</P> Thu, 05 Jun 2025 04:17:19 GMT juliusblash1 2025-06-05T04:17:19Z https://community.netapp.com/t5/ONTAP-Hardware/Convert-2240-4-to-Disk-Shelf/m-p/105155#M6519 <P>My company purchased a FAS2552 with SSD to add a Flash Pool to our current setup.

Just remove ownership of all the disks before decommission.
