The project addresses the replacement of already non-compliant system infrastructure components that are already technologically obsolete or their manufacturer has announced the termination of support, the expansion of the system infrastructure with new components, important for the performance of tasks and delegated activities of IROP for the following years, and also the restoration of non-compliant PC technology. Replacing and expanding the infrastructure will increase the performance, availability and functionality of the infrastructure. This will minimise the risk of data processing integrity being lost.
