porting and revision of IM to opencart

It is necessary to transfer the already ready-made IM to opencart (it is already on the new server, but there are a number of conflicts, including the inconsistency of the php version and other things, database versions, etc.), run, change the template, make a multi-menu with subcategories, install the SEO module, configure all screens and static pages. Or that it is faster and easier to transfer the database of products and categories to a ready-made clean assembly with a template and plugins:

Template preference: www.journal-theme.com/1/
SEO Preference: Paladin SEO
Preference for caching and acceleration: NitroPack

The app has a menu and the appearance you want to strive for.
