You need to download the production-ready version from the CloverDX portal, using your account and then proceed accordingly to our documentation. Providing you are upgrading to the same major version of CloverDX (CloverETL, e.g. 4.8.0-M1 to 4.8.0), the license valid in the milestone version will also be valid in the production version, so there is no need to re-download it. Please note that your CloverDX Server version has to match your Designer version.
Milestone versions contain new features for users to try out. These new features sometimes may not be as polished as we would like them to be for production ready releases. That’s why it it is not recommended to use milestone versions in a production environment. The database structure of production ready versions, following their milestone brethren, might not always be completely compatible, therefore, it is greatly advised to do a clean installation of the production version instead of upgrading the milestone version.
