What happens if I close my browser during an import?

Nothing bad. Imports run on Migratify's servers, so closing the tab, the browser, or your laptop doesn't interrupt them. When you open Migratify again, the progress bar picks up where the import actually is.

The only way to cancel a running import is the Stop migration button on the Import page. Note that only one import runs at a time, so a new import has to wait until the current one finishes or is stopped.

If products seem missing after an import, see Import is slow or products are not appearing.
