Hi Chris
I suggest you work with your Netapp Partner to arrange for some swing gear if possible. A DS2246 shelf or two will allow you to unpick the ADP and setup dedicated root aggregates for the FAS2552 controllers. From there a head swap should hopefully be straight forward.
We're in the initial phases of planning a controller upgrade for our FAS2552 clusters (also upgrading to FAS8200). We were fortunate that we had enough disks at the start to remove ADP. At the time it was very new and we were aware of the problems it would pose for a controller upgrade. I know that's not very helpful but if there's anything we learn in the process that might help you I'll pass it on.
It would also be great if someone from Netapp could chime in and clarify how customers are supposed to upgrade entry level SAS/hybrid systems with ADP, particularly switch-less clusters. I hope that Netapp will support FAS8200s running with R-D ADP setups that are upgrades from entry systems.
Good luck and please let us know if you learn anything from Netapp that could help others.
Steve

Root-data-(data) partitions are supported only on all-SSD systems; as you have SAS/SATA disks you cannot use them – at least in supported way.
Thanks for that insight, I really appreciate it. Feeling really let down by Netapp now for them to propose a solution that is unsupported! I will have words :(
