Set testwiki to use the new MCR-only schema
Closed, ResolvedPublic
Actions

Description

The following setting switches fully MediaWiki to the new, MCR enabled database schema for revision storage:

$wgMultiContentRevisionSchemaMigrationStage = SCHEMA_COMPAT_NEW;
NOTE: This marks the point of no return for MCR deployment to the testwiki: rolling this back will result in data loss on the test system.
