Architecture
Start with dependency mapping
Inventory applications, data stores, network trusts, and batch jobs. Surprises during cutover are expensive.
Prefer incremental strangler patterns
Route traffic gradually to new services while legacy systems remain authoritative until confidence is proven.
Dual-write carefully
When dual-writing, define reconciliation jobs and clear primary source of truth transitions.
Observability is non-negotiable
Dashboards, alerts, and rollback runbooks must exist before the first production cutover window.
