I’m testing the upgrade from the very old to the very new OJS. Since we need the supplementary files to be shown on the pages with the articles, following the advice given here, my upgrade sequence was 2.4.8-1 => 3.1.2-4 => 3.3.0-21 => 3.5.0-1.
Before the upgrade, the supplementary files were accessible through the reading tools block plugin via links such as https://journal.tld/rt/suppFiles/1234 (for the page with all of them) or https://journal.tld/article/downloadSuppFile/1234/2016 (for downloading the particular file). After the upgrade, the link to the same supplementary file became https://journal.tld/article/view/1234/6303
So I can’t now find a 1:1 correspondence between the old and the new URLs, can I? This is relevant because some time ago our editors have started to put the links to the supplementary files into the PDF galleys. As the URLs are quite different, after upgrade, we will be left with a bunch of broken URLs and no way of quickly hacking this via the web server redirects.
Am I right to assume that we’re screwed, ‘cause the URLs will have to be repaired manually by going to the article pages, finding the corresponding supplementary files, taking their URLs, and recreating and reuploading the PDF galleys with the right URLs?
