    The history of import substitution did not start last year after well-known events. Its launch dates back to 2014. It was from this year that state and near-state companies began to think of switching to the so called "recommended software". One of these companies approached us back in 2020 with a project to move from Oracle to PostgreSQL. This project was designed to solve the accumulated architectural problems (imperfect storage system for telemetry data, the DBMS itself worked inside a virtual machine), and optimize the use of disk space (make space in the main storage, debug saving archived data, ensure correct backup). Since the customer's system should have worked uninterrupted 24/7, it was necessary to switch from one DBMS to another "seamlessly" without downtime, with simultaneous operation of both to ensure step-by-step translation of subsystems and the ability to control the correctness of the data. And, of course, the work had to be completed as quickly as possible.

    In the report we will discuss how we managed to solve this case.
