 # Replicate data into Azure Database for MySQL Flexible Server
@@ -15,9 +16,9 @@ ms.date: 06/08/2021
 
 Data-in replication allows you to synchronize data from an external MySQL server into the Azure Database for MySQL Flexible service. The external server can be on-premises, in virtual machines, Azure Database for MySQL Single Server, or a database service hosted by other cloud providers. Data-in replication is based on the binary log (binlog) file position-based. To learn more about binlog replication, see the [MySQL binlog replication overview](https://dev.mysql.com/doc/refman/5.7/en/binlog-replication-configuration-overview.html).

 ### Data not replicated
 
-The [*mysql system database*](https://dev.mysql.com/doc/refman/5.7/en/system-schema.html) on the source server isn't replicated. In addition, changes to accounts and permissions on the source server aren't replicated. If you create an account on the source server and this account needs to access the replica server, manually create the same account on the replica server. To understand what tables are contained in the system database, see the [MySQL manual](https://dev.mysql.com/doc/refman/5.7/en/system-schema.html).

-Modifying the parameter `replicate_wild_ignore_table` used to create replication filter for tables, is currently not supported for Azure Database for MySQL -Flexible server.

 ### Requirements
 
 - The source server version must be at least MySQL version 5.7.
-- Our recommendation is to have the same version for source and replica server versions. For example, both must be MySQL version 5.7 or both must be MySQL version 8.0.
-- Our recommendation is to have a primary key in each table. If we have table without primary key, you might face slowness in replication.

+- Our recommendation is to have a primary key in each table. If we have a table without primary key, you might face slowness in replication.
 - The source server should use the MySQL InnoDB engine.
-- User must have permissions to configure binary logging and create new users on the source server.
+- User must have the right permissions to configure binary logging and create new users on the source server.
 - Binary log files on the source server shouldn't be purged before the replica applies those changes. If the source is Azure Database for MySQL refer how to configure binlog_expire_logs_seconds for [Flexible server](./concepts-server-parameters.md#binlog_expire_logs_seconds) or [Single server](../concepts-server-parameters.md#binlog_expire_logs_seconds)
 - If the source server has SSL enabled, ensure the SSL CA certificate provided for the domain has been included in the `mysql.az_replication_change_master` stored procedure. Refer to the following [examples](./how-to-data-in-replication.md#link-source-and-replica-servers-to-start-data-in-replication) and the `master_ssl_ca` parameter.
 - Ensure that the machine hosting the source server allows both inbound and outbound traffic on port 3306.
 - Ensure that the source server has a **public IP address**, that DNS is publicly accessible, or that the source server has a fully qualified domain name (FQDN).
-- In case of public access, ensure that the source server has a public IP address, that DNS is publicly accessible, or that the source server has a fully qualified domain name (FQDN).
-- In case of private access ensure that the source server name can be resolved and is accessible from the VNet where the Azure Database for MySQL instance is running.For more details see, [Name resolution for resources in Azure virtual networks](../../virtual-network/virtual-networks-name-resolution-for-vms-and-role-instances.md)
