Enable MCR migration stage "write both, read new" on commons beta.
Closed, ResolvedPublic

Description

To try out the new, MCR enabled database schema, we should enable the new retrieval code on a beta wiki first:

$wgMultiContentRevisionSchemaMigrationStage = SCHEMA_COMPAT_WRITE_BOTH | SCHEMA_COMPAT_READ_NEW;

This keeps writing to the old schema as well, so we can still easily back out of the migration.
Perhaps commons.wikimedia.beta.wmflabs.org would be a good choice.

NOTE: this requires populateContentTables.php to be run first.
