Thread:Project:Support desk/database is suffering from InnoDB corruption, specifically in the mw objectcache table./reply (5)

A broken table is a MySQL problem. MediaWiki however is not MySQL, it only uses MySQL, it is based on MySQL. If you upgrade MediaWiki or not will most likely not influence the problem in MySQL - I can only imagine that it makes this problem's impact on MediaWiki worse. Generally it is better to solve issues before changing anything additional in the system. I would first fix the broken tables and do the upgrade afterwards.
