You can upgrade your Standard Edition installation to a more recent version, or upgrade your Community Edition installation to the Standard Edition.

Note: Because of significant changes in version 1.2.6, if you plan to upgrade from version 1.2.5 or earlier to a version in the range 1.3.0 - 1.5.0, you must first upgrade to version 1.2.6. For example, to upgrade from 1.2.5 to 1.4.1, you first upgrade to 1.2.6 and then to 1.4.1. You can upgrade from versions 1.2.5 and earlier to 1.5.1 and later without first upgrading to 1.2.6.
