I have a MW instance that was updated from 1.21.something to 1.23.13. I didn't setup the old wiki, and it is no longer around for me to look at, but I have several references that look like <ref name=PMID:19957275/>. I realize this is not the current markup used by PubmedParser, but I was wondering if perhaps our old wiki used an older version of PubmedParser. If that is the case, will I need to update to a newer version of MW to get these references working again and if so, will the pages that use the older markup just work, or will I need to do some other stuff too?
Thanks.
