Upgrade and Migration Tooling

Description

Provides automated tools for upgrading the platform between minor and major versions, including pre-upgrade validation, database schema migration, configuration backup and restore, and rollback capability. Supports zero-downtime upgrades on Kubernetes deployments.

Canonical use case

A customer upgrades from ExpertFlow 4.x to 5.x using the migration tooling, which backs up all configuration, runs schema migrations automatically, and completes the upgrade during a maintenance window without any manual SQL intervention.
