There is a way. It requires manual partitioning of the SSDs. Then there is a cool command to redo the node root volumes.
That process uses Aggr Relocation to send all data AGGRs to the partner, then an automated process will create a new root on the ADP devices and restore the root volume back. You then repeat the other way.
It is not for the feint of heart!
There is a KB article, I am not sure if it is even customer facing. I may be able to dig up more if you'd like!
