Customer.io Upgrade & Migration

Output

• A staged migration record with schema/template compatibility, environment evidence, owner, and rollback decision.
• A preserved prior configuration and safe observation window before any irreversible cleanup.

Examples

Migrate a development workspace first using synthetic profiles and versioned event/template contracts. Verify delivery, consent, attributes, and observability before staging and production canaries. If compatibility or recipient behavior differs, roll back to the prior version and stop promotion; do not bulk-replay production events to test a migration.

Current State

!npm list customerio-node 2>/dev/null | grep customerio || echo 'customerio-node: not installed' !npm view customerio-node version 2>/dev/null || echo 'Cannot check latest version'

Overview

Plan and execute customerio-node SDK upgrades safely: assess current version, review breaking changes, apply code migrations, and validate with staged rollout.
