This migration will cause some unavoidable temporary user-visible impact: The sorting of some category pages will be distorted – all pages which have been updated with the new software version will use the new sorting while untouched pages still use the old sorting. As such, we need to run a maintenance script to update the sorting for old entries. The distortions may last from a few hours (on medium-sized wikis) to a few days (on the largest wikis), and the start-time will depend upon when the migration reaches each wiki..
