 necessary steps are detailed in this section. If it is not planned to replicate
 the master database, skip this section.
 
-#### Create technical user
-
-Connect to the MySQL database master and create a technical user to handle the
-replication:
-
-```sql
-CREATE USER 'repl' IDENTIFIED BY 'password';
-GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'repl'
-  IDENTIFIED BY 'password'
-  REQUIRE SUBJECT '/C=DE/O=Gerrit/CN=gerrit-db-slave';
-FLUSH PRIVILEGES;

-The username and password have to be the same as configured in the database slave's
-`values.yaml` under `mysql.replication.config.masterUser` and
-`mysql.replication.config.masterPassword`.
-
-The subject string has to be the same as the one used for the slave's certificate
-signing request. If SSL is not used, omit the subject requirement.

 #### Create database dump and note database state
