Some of the wikis that have already been updated have been curating buglists; if you maintain a wiki which gets upgraded and notice a bug, it may not hurt to check these buglists to see if it's already been noticed and whether staff appears to be aware of it. The lists I know of are w:c:yugioh:Forum:Upgrade problems and w:c:starwars:Forum:SH:MediaWiki 1.19 upgrade; I wouldn't doubt that there are others (so if you're aware of one, please link it here too).
