As you start to redesign your website to become mobile friendly here is a tool that will help.
I think the best thing to do is Hide all pages but the home page.
Do all your edits and then check to see if the site is mobile friendly.
Then unhide the next page and work on it.
and check a gain.
I think doing one page at a time will keep you on track and is the easiest way to get it done.
Hope this is of help.
