dotCMS has a different upgrade process for upgrading dotCMS Cloud vs Self Hosted dotCMS. There are a few steps that should be done no matter which type of enviroment you are upgrading.
Important: Review the changelog for the version that you are upgrading to.
The change log contains specific information on both the changes that have been made in the new version and how this may affect your individual dotCMS installation.One specific change to look out for is a Breaking Change, which will require change in your system or dotCMS implementation for the new version to work, this is noted at the top of the changelog for that particular release. Importantly, the change log for the new version may suggest additional upgrade steps you need to take, based on your individual dotCMS configuration.
- The changes are inclusive, so you should review all changes between the older version you are running and the newer version you are upgrading to.
- Please also review the list of deprecated macros and features to determine if any features in your installation have been newly deprecated.
- Version 21.06 is the last version of dotCMS to support Oracle and MySQL. If you use MySQL, this tool can simplify the migration from MySQL to PostgreSQL. It is believed to work in most cases, though it has not been tested with significantly old versions of the software. We still recommended, as we do generally, that you make backups before performing any major operation on a database.
