+### Database migrations failing because of batched background migration not finished
+
+When updating to GitLab 14.2 or later there might be a database migration failing with a message like:
+
+```plaintext
+StandardError: An error has occurred, all later migrations canceled:
+
+Expected batched background migration for the given configuration to be marked as 'finished', but it is 'active':
+  {:job_class_name=>"CopyColumnUsingBackgroundMigrationJob", :table_name=>"push_event_payloads", :column_name=>"event_id", :job_arguments=>[["event_id"], ["event_id_convert_to_bigint"]]}
+```
+
+To fix this error:
+
+1. Update to either 14.0.3 or 14.1.
+1. [Check the status](#check-the-status-of-background-migrations) of the batched background migration from the error message, and make sure it is listed as finished. If it is still active, either wait until it is done, or finalize it manually using the command suggested in the error, for example:
+
+```shell
+sudo gitlab-rake gitlab:background_migrations:finalize[CopyColumnUsingBackgroundMigrationJob,push_event_payloads,event_id,'[["event_id"]\, ["event_id_convert_to_bigint"]]']
+```
+
+1. You can now update to GitLab 14.2 or higher.
