To upgrade a module, follow these steps:
Check the module's documentation to ensure that it is compatible with your dmBridge version.
In the Modules section of the Control Panel, disable the current module.
Back up the old module folder and install the new one in its place.
Optionally, if your module uses a database, back that up as well. Ensuring data integrity is the responsibility of the module's author.
In the Modules section of the Control Panel, enable the new version of the module.
