zero-downtime migration
What is a zero-downtime migration?
The definition
Migrating with zero downtime means running the old and new product side by side, then switching customers over once everything is verified. Your users notice nothing, except that the app is faster. Rolling back stays possible until the last moment.
Why it matters to you
You don’t close up shop during the work.
The switch is rehearsed with a dry run before it’s done for real.
It happens in one night, not in an on-call weekend.
A real-life example
A platform its customers use every morning changed foundations on a Tuesday night. By Wednesday, nobody had noticed anything, except that pages opened faster.
And in your case? ?
Thirty minutes on a video call to look at your product and tell you what we think.
