To uninstall a module, remove the module JAR file from the /WEB-INF/lib
folder and restart Magnolia.
However, this is rarely enough. Modules add and modify configuration during installation. The use of a module also changes content. Removing all of these changes is difficult without knowing the installation tasks in detail. To test a module, use the embedded Derby database and take a backup of your repositories
folder. Install the module and try it. When you are done testing, remove the module JAR and restore the repositories
folder from the backup. This way you can go back to square one. We also recommend that you segregate the development and production environments. Take regular backups for disaster recovery so you can revert to a prior state in a routine fashion.
