How to Migrate Away from Fly.io

Nothing else in this process matters if the copy step gets skipped, so before touching a single setting in Fly.io, get your data out and store it under your own control, a local drive, your own cloud space, anywhere that is not the product you are about to leave. People rushing for the exit routinely omit this, and it is precisely what turns a botched migration from a recoverable annoyance into a permanent loss.

An export you cannot open elsewhere is not really an export, so the question to settle first is what Fly.io lets you take with you and in which formats. The product's own data-download or export page is the authority here, check it before cancelling anything, because subscriptions and access to your own material commonly end together. Prefer the widest, most standard format on offer over anything proprietary, since the whole point is that the next tool, whichever it is, can read what you pull out.

The useful way to shortlist against Fly.io runs backwards from the obvious one: name the single thing you cannot give up before you open any list of rivals, then hold every other hosting & deployment option against that one line. Fly.io concentrates on cloud-infrastructure and paas, so a genuine alternative either serves that same need more precisely or covers ground Fly.io leaves open. Research two candidates properly rather than skimming eight, because a shortlist you have actually tested beats a long list you only read about. Our comparison pages cover named hosting & deployment rivals in more detail when you reach that stage.

Importing into a new hosting & deployment tool rarely lands perfectly on the first attempt. Bring a small, representative slice across first and check it looks right before committing the whole set, because fixing a structural mistake at full volume costs far more than a second pass on a sample.

Closing the Fly.io account is the last step, not a formality, so earn it with evidence: the counts on both sides agree, the specific items you rely on open cleanly in the new tool, and a spot check turns up nothing that vanished in transit. Until the replacement has carried genuine work long enough to earn your trust, leave the old account standing, downgraded is fine, gone is premature.
