Installing Plugins and Scripts

[Leopardo-40]

Good evening to the entire Forum.
I am a new member of this Forum but I have been using Gimp for several years, where I am part of several Forums (GimpChat, is an example) in the field.
I want to migrate to Gimp 3.0, but I don't want to lose some of the Scripts and Plug-ins that I have in Gimp 2.10.38, so my question is.
Where and how do I place the Plug-ins? and the Scripts? from Ofnuts In 2.10.38 I know, but in this new one, I'm confused.
Thanks..

Plug-ins (binaries and Python) you have for 2.10 won't work in 3.0. They have to be rewritten/converted(*).  And in the general case this also applies to any non-trivial script-fu script.

(*) For Python, because the GIMP API has changed, but also because we go from Python v2 to Python v3 and the language is a bit different (for the better, I'd say)

I mean, Scripts like this, (ofn-bend-path) or other Phats you have don't work on 3.0.0?
