The EU Data Act's switching rules are set to eliminate cloud switching charges, including data egress fees, from 12 January 2027. How much does that change the cost of moving providers, and what expenses will still matter?
Will the EU Data Act make cloud migrations much cheaper?

It removes a potentially expensive line item, not the cost of the migration itself. Converting schemas and testing integrations can take a lot of work, especially when applications depend on services that behave differently at the destination.
I'd compare the egress charge with the engineering and testing estimate before deciding whether waiting changes the calculation. The transfer bill is only one part of the move.

Data volume still matters. A business with years of rarely accessed logs kept for regulatory retention may have a lot to move. Removing the departure fee doesn't make the storage or the work of handling that data free.

Don't forget the overlap bill. If both environments need to run while the new one is tested and the cutover happens, you're paying for both for a while. The length of that overlap can make a big difference to the budget.

Authentication can need rewiring too. That work is easy to miss if the estimate focuses on moving databases.
