Help for Signature and OTA on the same node, How To

[sindrome73]

Good morning!! I need a clarification, I have some MySensors nodes that work regularly, and on some of these I have also activated the Firma Software, so far all Ok.
Now, as a matter of convenience, I am introducing the OTA overruns.
My question is, in a node with a signature to which I want to add OTA, how to proceed ???

1. I customize the Node
2. Load the new Bootloader
3. Load the new sketck via OTA

it's correct?? or are the steps to follow others?

Thanks to those who want to clarify my ideas
