I would suggest upgrading your CLI - the online resource generator was sunsetted almost a year ago.

Will that update the ionic base to V4/5 ?

I’m still workirng on some projects on 3

I don’t know what you mean by “the ionic base”, but the framework that is bundled with your apps is local to each app, and therefore independent of the globally installed CLI.

If I do an upgrade of the cli, will it upgrade Ionic from 3 to latest version ?

I dont want to do that cause it will mean I will have to rewrite the apps I am working on, I just want to export this one and publish
