No, the squashed migration should be used in place of the old ones for any new database, even if the old ones are still present. This is the point of the squashmigrations feature; that you can keep the old ones around (which is necessary for any deployments that may not yet have applied all of them) while still gaining the benefit of the new squashed migration for new deployments (and tests). I know this works, because I just did it recently myself. It sounds like Cherie was able to get it working too, though we didn't get any clarification on why it didn't seem to work originally. > In the documentation: > "This enables you to squash and not mess up systems currently in > production that aren’t fully up-to-date yet.

That's right. The length of time you need to wait before removing can vary widely. For a third-party app, it may be a full release cycle or two (as long as you can tell your users to upgrade version-by-version). For a project with only a few deployments, all under your control, it may be the same day. But regardless, the squashed migration will still be used in tests immediately, before you remove the old migrations.
