How Does MgC Generate Target Database Recommendations?

MgC can assess and generate recommendations for MySQL, PostgreSQL, MongoDB, Oracle, and SQL Server databases.

The following table describes the recommended versions during database assessment.

Cross-version migration may fail if there are compatibility risks. Before the migration, evaluate risks and back up all data.

**Table 1** Recommended versions for different databases
Database Type	Description
MySQL	If the source database version is earlier than 8.0, MySQL 5.7 is recommended. Otherwise, MySQL 8.0 is recommended.
PostgreSQL	The recommended target database version is preferably the same as the source database version. Note that PostgreSQL 12 and earlier versions are no longer available on Huawei Cloud. We will display all available versions on Huawei Cloud for you to choose.
SQL Server	The recommended target database version is preferably the same as the source database version. If the source database version is missing, SQL Server 2022 is recommended.
MongoDB	The recommended target database version is preferably the same as the source database version. If the source database version is missing, MongoDB 4.2 is recommended.
Oracle	The recommended target database version is preferably the same as the source database version. If the source database version is missing, GaussDB V2.0-3.226 Enterprise Edition is recommended.
