Zero-downtime migration is a migration where customer sign in stays available throughout the transition, with no cutover window during which customers lose access.
Frequently asked questions
Which migration approach attains zero downtime?
Just-in-time migration is built around this. Each customer's account moves over the moment they sign in, rather than cutting over every account at once on a fixed date.
Does zero-downtime migration still require planning?
Yes. It still requires an integration between the new product and the legacy system, along with testing and monitoring throughout the transition.
