I am submitting a manuscript to PNAS and they want to know if the work is in arxiv or a preprint server (a definite yes or no).

A few months ago, we had posted a much older version of the manuscript to arxiv under a different name.

I know that the arxiv version can be replaced, but a different author (the PI) had posted it there. Since the PI is busy right now, getting them to update the arxiv version may take quite a few days. But, I want to speed up the journal submission process (my PI and other coauthors have contributed to the updated version, and they have agreed that I, the first author, will send the new version to the journal). What should I do now?

Alternatively I can just give a link to our old preprint and proceed immediately. The same arxiv link will be eventually updated to the new version anyway, and the journal should send my uploaded PDF to the referees, not the arxiv version. What worries me is whether the editors may not like it if they find out that the submitted article title and the preprint title are different and the content is also somewhat substantially different.
