This document describes the process of migrating the system from version 1.3.1 to version 1.4.0.
Migration includes updating the PostgreSQL and ClickHouse database schemas, as well as transferring data.
Before starting the migration, be sure to back up all data as described in Preliminary steps section |
Recommended resources for successful migration (based on a system with 3,000 employees, 2,200 passes, and 300 cameras):
Use Migration on the current server scenario if the update is performed on the same server where the system with version 1.3.1 is already running. |
Use Migration on a new server scenario, if the migration is performed on a new clean server. |
