   * Ensure that the user has “REPLICATION CLIENT” and “REPLICATION SLAVE” permissions on the source server for reading and applying the bin log.
   * If you're targeting a online migration, configure the binlog_expire_logs_seconds parameter on the source server to ensure that binlog files aren't purged before the replica commits the changes. We recommend at least two days to start. After a successful cutover, you can reset the value.
 * To complete a schema migration successfully, on the source server, the user performing the migration requires the following privileges:
-  * “READ” privilege on the source database.
-  * “SELECT” privilege for the ability to select objects from the database
-  * If migrating views, the user must have the “SHOW VIEW” privilege.
-  * If migrating triggers, the user must have the “TRIGGER” privilege.
-  * If migrating routines (procedures and/or functions), the user must be named in the definer clause of the routine. Alternatively, based on version, the user must have the following privilege:
-    * For 5.7, have “SELECT” access to the “mysql.proc” table.
-    * For 8.0, have “SHOW_ROUTINE” privilege or have the “CREATE ROUTINE,” “ALTER ROUTINE,” or “EXECUTE” privilege granted at a scope that includes the routine.
-  * If migrating events, the user must have the “EVENT” privilege for the database from which the events are to be shown.
+  * [“SELECT”](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_select) privilege at the server level on the source.
+  * If migrating views, user must have the [“SHOW VIEW”](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_show-view) privilege on the source server and the [“CREATE VIEW”](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_create-view) privilege on the target server.
+  * If migrating triggers, user must have the [“TRIGGER”](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_trigger) privilege on the source and target server.
+  * If migrating routines (procedures and/or functions), the user must have the [“CREATE ROUTINE”](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_create-routine) and [“ALTER ROUTINE”](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_alter-routine) privileges granted at the server level on the target.
+  * If migrating events, the user must have the [“EVENT”](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_event) privilege on the source and target server.
+  * If migrating users/logins, the user must have the ["CREATE USER"](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_create-user) privilege on the target server.
+  * ["DROP"](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_drop) privilege at the server level on the target, in order to drop tables that might already exist. For example, when retrying a migration.
+  * ["REFERENCES"](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_references) privilege at the server level on the target, in order to create tables with foreign keys.
+  * If migrating to MySQL 8.0, the user must have the ["SESSION_VARIABLES_ADMIN"](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_session-variables-admin) privilege on the target server.
+  * ["CREATE"](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_create) privilege at the server level on the target.
+  * ["INSERT"](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_insert) privilege at the server level on the target.
+  * ["UPDATE"](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_update) privilege at the server level on the target.
+  * ["DELETE"](https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_delete) privilege at the server level on the target.
