• Recreate the index with the new mapping
• Restart swh-search service
• Copy the backup of the index done in #2780 (closed)
• Restore the swh.search.journal_client consumer group offsets to migrated/migration$941
• Reset the swh.search.journal_client.indexed consumer group offsets to the beginning
• restart the service and the journal_client
• wait for the backfill completion
