 Until 2018, CineSat migration to new operating systems and computer architectures has been mainly driven by the server hardware and operating systems used at major customer sites - typically RedHat Enterprise Linux 5 32-/64-bit bi-architectures. While these legacy servers are meanwhile being operated well beyond their hardware life-time and operating system life-cycles, the technical requirements for the CineSat application have continuously increased with availability of new meteorological data, e.g. Until 2018, CineSat migration to new operating systems and computer architectures has been mainly driven by the server hardware and operating systems used at major customer sites - typically RedHat Enterprise Linux 5 32-/64-bit bi-architectures.

Extended support of old 32-bit systems beyond 2018 will only be possible under a dedicated __Extended Lifecycle License__ and will be limited in time, as well as in functionality and in keeping track with latest input data formats. +Therefore, the 2019 CineSat releases will be based solely on up-to-date 64-bit operating systems.
