Upgrade from OJS to, static pages

We have had in OJS menu in Boostrap theme which we created by editing navmenu.tpl. That menu was actually static page in which there were several other static pages.

As far as I See after uopgrade all those static pages are listed in navmenu manager. I guess I shoudl recrerate menu using Navigation menu Manager and connect those “menus” or copy/paste content into static page by newly created menu. Correct?
