moving a basic application to advanced front-end

Hello;

I’ve an application already developed using basic template; I would like to move it to the front-end of advanced template.

Is that possible? any idea on how I can procede?

In my basic application I installed some extension too.

Yes. It’s possible. What you need to look for is namespace changes i.e. app becomes frontend. The rest should be quite compatible.

Thanks; so for the extensions; will I have to replace the advanced template vendor for with the one of my current project?

No. Don’t copy vendor over. What you need is a list of dependencies for composer.json. Run composer update in root dir where composer.json is and vendor will be filled with what you’ve specified.
