Migration cost and downtime

A channel manager migration is one of the most disruptive operational projects a hotel undertakes. Done well, it takes 4-6 months end-to-end with 24-48 hours of cutover downtime. Done badly, it produces 90 days of double-booked nights, missing inventory, and emergency reservations work that consumes the entire commercial team. Understanding the cost structure before signing is what separates the two outcomes.

The cost structure

Total realistic budget

A 240-key property migrating from CM A to CM B should budget €80k-€250k of true total cost, not the €30k the vendor invoices. Most properties underestimate by 2-3× because they only count the invoice line items.

What good migration discipline looks like

When NOT to migrate

Migrate only when the strategic case is clear and the cost is justified by quantified business benefit. Migrating because the CEO read a blog post about a new CM, or because the KAM at the new vendor offered good pricing, or because the current CM has a bug that could be fixed with a configuration change — these are not migration triggers. They are signs of poor diagnostic discipline.
