The Migration Checklist

A migration checklist systems operations team can actually follow is the difference between a smooth transition and a week of chaos. Every system migration I have done taught me something. Most of those lessons came from things going wrong.

This checklist exists so you learn from my mistakes instead of making your own.

Before You Start

Inventory everything the old system does. Not what you think it does. What it actually does. Check every automation, every integration, every scheduled task. Old systems accumulate hidden functionality that nobody remembers until it stops working.

Document every data format and every connection point. The CRM feeds the email tool which feeds the reporting dashboard. Map every link in the chain.

Identify the people who depend on the system. Ask them what they use it for. They will tell you things that are not in any documentation.

The Migration Plan

Run the old and new systems in parallel. Never cut over all at once. Route 10% of traffic or activity to the new system first. Monitor for problems. Gradually increase until the new system handles everything.

Set success criteria before you start. What does "working" look like? Response times, data accuracy, integration functionality, user satisfaction. If the new system does not meet these criteria, you have a clear signal to pause.

Build a rollback plan. If the new system fails, how do you go back to the old one? How long does rollback take? What data might be lost? If you cannot answer these questions, you are not ready to migrate.

During Migration

Check data integrity at every step. Compare records in the old system to records in the new one. Missing records, wrong formats, and broken relationships show up here.

Test every integration. Do not assume that because the old system talked to your email tool, the new one will too. Test it. With real data. In a staging environment first.

Communicate with your team. Daily updates during migration. What is working, what is not, what is next. Surprises destroy trust. Transparency builds it.

After Migration

Do not turn off the old system immediately. Keep it running in read-only mode for at least 30 days. When something looks wrong in the new system, you need the old one for comparison.

Run your full QA checklist. Every report, every automation, every integration. Check the edge cases, not just the happy path.

Collect feedback from users after one week and again after one month. Their experience is the ultimate test.

A good migration checklist systems operations approach is about reducing risk at every step, not about moving fast.
