#Upgrade/Extending single node cluster to ha cluster

We have an old FAS2500 single controller with just local disks in the chassis.
We would like to upgrade this to a FAS2600HA. Not sure if this is even described no the support site? But isn't it just as easy as shutting down the node, replacing the controller with a FAS2600, assigning the disks and booting? Then add the other node to the cluster.. For this we will need to add disks for the other nodes root disks... which I guess is just assigning the disks you would like to use to the new controller, then boot into the menu and running the init on the disks, and join the other cluster... (of cause all ontap versions has to be the same etc...) The current controller is on 9.8. I can see that this version have the "cluster controller-replacement" option... but do you need to use this?

it depends. There are some FAS25xx chassis where the FAS26xx controllers physically don't fit (they have a key slot on the right side that stops SBB 2 canisters being inserted into an SBB 1 chassis). In that case you need to change the chassis. OTOH I have heard from people where that upgrade path worked just fine 🤷‍♂️
