![]() ![]() Alternatively, you can perform a purely logical upgrade by dumping only the user schema(s), and loading them into a fresh MySQL instance at the new version. There are 2 basic options available when upgrading from one mysql instance to another:Ī ‘Dump’ Upgrade involves dumping the data from your existing mysql instance using mysqldump, loading it into a fresh MySQL instance running the new version (e.g. Validation includes ensuring the stability of the mysql server, reviewing integrity of the data, and testing functionality at all stages. This also includes tests involving replication between versions. We test and validate each topic at the initial, upgraded, and downgraded stages of the process. We also create new test cases for every release as needed. In these cases, we run through an extensive set of test cases involving users, privileges, tables, views, procedures, functions, datatypes, partitions, character sets, triggers, the Performance Schema, the mysql schema, the sys schema and more. We test upgrading from one version to the next quite extensively during each release cycle to ensure that all user data and settings are safely and successfully upgraded. This allows the upgrade process to apply the changes for one major release at a time. For example, if you are at 5.1.73, and you want to go to 5.7.9, the safest and recommended method is to upgrade from 5.1.73 to 5.5.46 (the latest 5.5 release at the time of this writing), and then upgrade from 5.5.46 to 5.6.27 (or any version of 5.6), then upgrade from 5.6.27 to 5.7.9. The general recommendation is to perform the upgrade by stepping from one major release to the next, without skipping an intermediate major release. To accomplish that task, we have provided a utility and documentation to upgrade from one version of MySQL to another. Upgrading MySQL is a task that is almost inevitable if you have been managing a MySQL installation for any length of time. NOTE: This blog is an updated version of the previously published blog, Upgrading Directly From MySQL 5.0 to 5.6 With mysqldump, modified for upgrading to 5.7. ![]()
