The ParserMigration extension was introduced in gerrit:296182. It provides an interface for comparing article rendering with a new non-default version of the MediaWiki parser thus serving as a parser migration tool.
It was deployed on the Wikimedia production cluster until 2018 to compare Tidy-based output with a RemexHTML-based output. RemexHTML was the replacement for Tidy. In 2023 it was redeployed in order to compare legacy wikitext parser output with output generated by the Parsoid wikitext parser.
The availability of the tool can be controlled by a user via the "parsermigration" preference option.
