GitLab → Harness migration — your questions answered

How do you handle my existing GitLab Bash scripts during migration?+

We refactor them into modular Harness templates, preserving all logic while enabling reusability and easier maintenance.

Can I keep GitLab support while migrating to Harness?+

Yes, your vendor contract remains active – so you move at your own pace with full GitLab support until you’re ready.

What if my GitLab support renewal lapses?+

If your GitLab renewal lapses, our third-party support covers most operational issues on the legacy platform while you complete the move.

How long does a GitLab to Harness migration take?+

Typical projects run 2–4 months with a two-senior-engineer team, on a fixed budget of $50,000–$320,000.
