Enterprise production deployments of HxGN NetWorks Core and HxGN NetWorks Core | Mobile often involve hundreds, or even thousands, of users running several different client applications (for example, desktop, web, mobile). Upgrading all users simultaneously to a new NetWorks Core version can present real challenges for a company’s IT organization and business operations. When new versions of HxGN NetWorks Core | Mobile are made available, compatibility of client applications with previous maintenance releases of the same release version and, when possible, previous release versions is maintained. This allows flexibility in making upgrade roll-out plans for client users.
Much effort is applied to have newer versions compatible with lower versions of other NetWorks Core client applications. Version compatibility is not always possible due to factors such as adoption of new technologies or architectures. If mixed-version compatibility is not possible, this is communicated in the HxGN NetWorks Core | Mobile Release Notes delivered with the product and posted to the Support website when the new software is made publicly available.
-
In general, software from a quarterly update runs alongside other components of the system that remain at the base major release version.
-
Any new functionality available in a new release may not function in a mixed-version environment.
The following sections provide specifics of mixed-version compatibility support with various combinations of NetWorks Core products and releases.
The term database in these sections refers to the metadata structure, as well as the database packages and procedures.
If you upgrade the database, the administrative users must operate with that same version of software to use metadata or to use API functions provided in the release.
If you do not upgrade the database, new software that relies on the new metadata does not operate.
