We've replaced a few metrics but want to compare the old and new metrics for consistency. If there are any interesting artifacts, somehow archive the old metrics. Otherwise, purge them.
- Media[wW]iki.CodeMirror.preferences.byPreference.*.byEnabled.*.byWiki.*
- MediaWiki.CodeMirror.sessions.byEditor.*.byEnabled.*.byWiki.*
- MediaWiki.CodeMirror.toggles.byEditor.*byEnabled.*.byWiki.*
Don't remove any of the metrics with byEditCount in the path.
