+### Pause batched background migrations in GitLab 14.x
+
+To pause an ongoing batched background migration, use the `disable` command above.
+This command causes the migration to complete the current batch, and then wait to start the next batch.
+
+Use the following database queries to see the state of the current batched background migration:
+
+1. Obtain the ID of the running migration:
+
+ ```sql
+ SELECT
+ id job_class_name,
+ table_name,
+ column_name,
+ job_arguments
+ FROM batched_background_migrations
+ WHERE status <> 3;
+ ```
+
+1. Run this query, replacing `XX` with the ID you obtained in the previous step,
+ to see the status of the migration:
+
+ ```sql
+ SELECT
+ started_at,
+ finished_at,
+ finished_at - started_at AS duration,
+ min_value,
+ max_value,
+ batch_size,
+ sub_batch_size
+ FROM batched_background_migration_jobs
+ WHERE batched_background_migration_id = XX
+ ORDER BY id DESC
+ limit 10;
+ ```
+
+1. Run the query multiple times within a few minutes to ensure no new row has been added.
+ If no new row has been added, the migration has been paused.
+
+1. After confirming the migration has paused, restart the migration (using the `enable`
+ command above) to proceed with the batch when ready. On larger instances,
+ background migrations can take as long as 48 hours to complete each batch.
