abstract = {The ATLAS and CMS cryogenic control systems have been operational for more than a decade. Over this period, the number of PLCs faults increased due to equipment ageing, leading to systems failures. Maintenance of the systems started to be problematic due to the unavailability of some PLC hardware components, which had become obsolete. This led to a review of the hardware architecture and its upgrade to the latest technology, ensuring a longer equipment life cycle and facilitating the implementation of modifications to the process logic. The change of the hardware provided an opportunity to upgrade the process control applications using the most recent CERN frameworks and commercial engineering software, improving the in-house software production methods and tools. Integration of all software production tasks and technologies using the Continuous Integration practice allows us to prepare and implement more robust software while reducing the required time and effort. The publication presents the current status of the project, the strategy for hardware migration, enhanced software production methodology as well as the experience already gained from the first implementations.},
