Guide
A practical framework.
Use this guide as a starting point for requirements, implementation planning or an architecture review.
1. Inventory the legacy program
List journeys, audiences, templates, integrations, data fields, reporting and operational dependencies.
2. Classify what moves
Decide what to migrate, redesign, consolidate or retire based on value and platform fit.
3. Map the new architecture
Define identity, events, attributes, subscriptions, integrations and journey patterns before rebuilding.
4. Test the cutover
Run data, journey, content, tracking, suppression and rendering validation with clear go/no-go criteria.
5. Stabilize after launch
Monitor early traffic and engagement, resolve issues quickly and document the new operating model.
Need help applying this?
HISOLIT can turn the framework into a scoped implementation, migration, architecture review, QA program or managed delivery workstream.
Migration quality depends on mapping, reconciliation and controlled cutover. Inventory users, attributes, events, subscriptions, templates, catalogs, integrations and reporting dependencies before rebuilding journeys. Run representative data reconciliation, parallel validation and rollback planning so production activation is based on evidence rather than assumptions.
