Are these node servers still needed?

[bw23198]

After migrating from ISY994 to eISY, and reinstalling all of my node servers, I have the following two node servers "left over" from my previous installation:

isylink

ISY Portal

Are these still needed?  If not, how do I delete them?  There used to be a delete button but none of my node servers had that button post upgrade.

Isylink is NodeLink and is not managed inside PG3x. You can remove it from AC Nodeservers if you’re not longer using it.

I think ISY portal was original integration to Alexa. Can delete it at same way if not using.

Isy portal is needed if you're running the occupany items in the portal.
