Is there a way to use bindings that was created for openhab 2 in the current versión?

I am trying to update my openhab to the current version, however one of the bindings I am currently using which is the ISY binding never got updated past openhab2. I know there is an insteon binding which I could use, however I am looking for the possibility to keep using the ISY binding.

Is there any possible way to do this?

Sorry, but there isn’t.
To many things have changes since openHAB 2.x, so it is not that easy to implement those changes into the ISY binding.
Best practice would be to ask the Insteon binding author to implement the features you think are missing.

You can run an OH2 and OH4 instance and integrate them using the Remote openHAB Binding:
