Yes this page i found already but this is confusing me:
"After you install and boot the new nodes and reassign disks, you must restore configuration information from the root volume to the boot devices."
I have a "empty" 2650 (i had inserted temporarily 6 disks to install the same ONTAP and test the system) , i want to put all 24 internal drives, which includes the root partition, from the 2240 to the 2650, change the owner of the drives and hope it will boot from the moved disks.
Normaly i will say it must work, but perhaps i have missed something...
You have a problem though... the minimum root volume size is 180GB on FAS2240-2, but 350GB on FAS2650. You can't just re-use the existing root partitons, unless you have additional storage you plan to add.
