Amazon RDS accommodates new Major Version Upgrade feature.
Henceforth through this new
release, those who are familiar, have the ability to upgrade existing RDS
database instances from
MySQL 5.1 to MySQL 5.5 using Amazon RDS new Major Version Upgrade feature.
MySQL 5.1 to MySQL 5.5 using Amazon RDS new Major Version Upgrade feature.
To upgrade, just simply select
the instance in the AWS Management Console, choose the Modify option, and select the latest version of MySQL 5.5 (you
cannot upgrade to earlier versions).
Here's a complete process:
1.
Read the MySQL 5.5 release notes and verify that none of the changes will affect your application.
2.
Launch a
test database instance and verify that your application runs as expected.
Amazon RDS makes this easy: you can create a snapshot of your running instance,
create a new instance from the snapshot, upgrade it to MySQL 5.5 using the Modify command, and do your testing.
3. Modify your
production database.
