The 26-Item Microsoft Fabric Migration Checklist: What Most Teams Get Wrong
A practical Microsoft Fabric migration checklist covering planning, governance, capacity, security, and migration readiness.
Most Microsoft Fabric migration failures aren't caused by the technology. They're caused by steps that were known, documented somewhere, and skipped anyway - usually because the project was already moving before anyone wrote them down. We built a 26-item Microsoft Fabric migration checklist after watching the same handful of gaps show up project after project, across assessment, architecture, governance, execution, and post-migration optimization. This post walks through five of those items in depth - the ones most consistently skipped, and what skipping them actually costs.
Why Migration Checklists Get Skipped, Not Failed
Nobody sets out to skip a checklist item. What actually happens is more mundane: a step gets deferred because "we'll circle back to it," the deferral becomes permanent once the project has momentum, and the gap only becomes visible three months post-go-live when a report breaks, a capacity throttles, or a security review flags a workspace nobody owns. The pattern holds across almost every Fabric implementation checklist gap we've seen - the mistake was rarely ignorance. It was sequencing.
5 Checklist Items Most Teams Get Wrong
Every one of these items was known in advance on every project where it caused a problem. The gap was never information - it was sequencing something before the migration had momentum, instead of catching it after.
What's in the Full 26-Item Checklist
The five items above sit inside five broader categories that make up the complete checklist - 26 items in total, covering the full arc from first discovery conversation to steady-state operation:
- Define migration goals and success metrics
- Secure executive sponsorship and funding
- Measure data volume and growth rates
- Map success metrics to technical tasks
- Identify existing tool sprawl to consolidate
- Choose medallion vs. simplified layer design
- Plan OneLake Shortcuts for external sources
- Decide Delta vs. Iceberg table strategy
- Design semantic model ownership
- Map legacy ETL logic to Fabric equivalents
- Assign Business Owner, Data Steward, Tech Owner per domain
- Set up Purview scanning and sensitivity labels
- Build a reconciliation and pipeline-testing framework
- Plan legacy system decommissioning
- Establish CU consumption showback by team
- ...and 6 more
- Nearly every Fabric migration problem we see traces back to a known step that got deferred, not a technology limitation.
- Sizing and governance decisions made before migration begins are dramatically cheaper than the same decisions made after workspaces and capacity usage have already sprawled.
- Migrating by use case, not by "big bang," is the single highest-leverage sequencing decision in the entire checklist.
- Capacity governance (auto-pause, quotas, CU monitoring) belongs in the pre-go-live checklist, not the post-launch backlog.

The five items covered here are the ones we see skipped most often - but they're five out of twenty-six, and the gaps that don't make this list still cause real delays and real budget overruns. If you're scoping a migration now, or mid-way through one and want a gut-check against what you might have missed, the full checklist is free to download and built to be run item by item against your own project, not read once and filed away.
