How to Migrate to MBSS Light: Step-by-Step Checklist
1. Prep and assess (Day 0–2)
- Inventory: List current systems, data types, integrations, and users.
- Goals: Define success metrics (downtime ≤ X, data integrity 100%, user adoption ≥ Y).
- Compatibility: Confirm MBSS Light supports needed features/APIs.
2. Plan migration (Day 3–5)
- Scope: Choose full vs. phased migration.
- Timeline: Schedule low-traffic window(s).
- Stakeholders: Assign owner, technical lead, and communication lead.
- Backups: Create full backups and verify restore process.
3. Map data & workflows (Day 6–8)
- Schema mapping: Map source fields to MBSS Light fields.
- Transform rules: Define data cleaning, normalization, and deduplication steps.
- Integration points: Document APIs, webhooks, and third-party connectors.
4. Build migration tools (Day 9–12)
- Scripts/connectors: Develop ETL scripts or use available connectors.
- Test harness: Create test datasets and an isolated MBSS Light sandbox.
- Logging & rollback: Implement detailed logs and reversible steps.
5. Test migration (Day 13–16)
- Dry run: Run full migration on sandbox; validate data integrity and workflows.
- Performance test: Measure import throughput and system load.
- User acceptance: Have key users verify core functionality.
6. Prepare go-live (Day 17–18)
- Finalize cutover plan: Step-by-step sequence, timing, and responsible persons.
- Communication: Notify users about downtime, changes, and support channels.
- Support ready: Staff support team and prepare quick-reference guides.
7. Execute migration (Day 19)
- Lock source if needed: Pause writes to ensure consistency.
- Run migration: Monitor logs, errors, and performance.
- Verify: Check record counts, key samples, and integrations.
8. Post-migration validation (Day 20–21)
- Smoke tests: Confirm critical workflows function.
- Data audit: Run checksums/sample comparisons for integrity.
- Issue triage: Fix high-priority defects immediately.
9. Optimize & train (Week 4)
- Performance tuning: Adjust settings, indexing, and workflows.
- User training: Run live sessions, distribute FAQs and how-tos.
- Monitor adoption: Track usage metrics vs. goals.
10. Closeout & documentation (Week 5)
- Document: Final architecture, runbooks, and lessons learned.
- Rollback decommission: Decide when to decommission old systems.
- Post-mortem: Hold retrospective and capture improvement items.
Notes:
- Adjust timelines for data volume and complexity.
- If integrations or compliance requirements exist, add legal/IT approvals to the plan.
