Lifecycle, DevOps & Migration
Lifecycle
Design:
Develop → Validate → Transport → Release → Monitor → Improve
Separate environments and responsibilities according to enterprise risk.
Migration
Use the Phase 22 migration factory:
Discover → Assess → Design → Build → Reconcile → Cut over → Stabilize → Retire
Release gate
A release should demonstrate:
- functional correctness
- semantic correctness
- security correctness
- performance acceptance
- reconciliation evidence
- rollback readiness
- operational ownership
Coexistence
During modernization, define the system of record and authoritative semantic layer explicitly.
Do not allow temporary migration pipelines to become undocumented permanent architecture.
Architecture runway
Maintain a backlog for capabilities that are not required for the current release but materially improve the target architecture later.
