-The Seafile Pro container needs to be running during the migration process, which means that end users may access the Seafile service during this process. In order to avoid the data confusion caused by this, it is recommended that you take the necessary measures to temporarily prohibit users from accessing the Seafile service. For example, modify the firewall policy.
+Add `[INDEX FILES]` section in `/opt/seafile-data/seafile/conf/seafevents.conf` manually:
 
-Run the following command to run the Seafile-Pro container：
-
-```sh
-docker compose up -d

-Then run the migration script by executing the following command:
