To update to the latest version, you must not update to every single version between. You can make a direct update to the highest version - e.g. version 1.0.3 to version 2.0.4
This page refers to module version 1.x. This concerns only versions from 2017. Documentation for current versions can be found here.
Upgrade from Version 1.x to Version 2.x
To upgrade the module, simply upload the new module archive.
Starting with version 2.0 the settings are managed through the module setting pages. All settings will be automatically migrated upon updating the module.
After you have uploaded the new files, you can optionally remove the files "customconfig.php", "licensekey.php", "classes.php", "functions.php" from the /modules/servers/dedicated/ directory.
To complete the upgrade, follow the normal installation guide.
