Switching from DALL·E without the drama
- Export your data from DALL·E first — most tools above can import standard formats.
- Run your top pick in parallel for a week or two before committing; self-hosted options can be tried locally in minutes.
- Migrate one team or one project at a time, keeping the old account read-only until everything checks out.
