Can I run my old auth system and Clerk simultaneously?

Yes, the skill includes a 'Parallel Running' phase with middleware configurations that allow your application to recognize both legacy sessions and Clerk sessions during the transition period.

Will my users need to reset their passwords after migrating?

Yes. Because most auth providers do not allow the export of raw password hashes, this skill includes a strategy to skip initial password requirements so users can set new ones upon their first login.

Does this skill handle API rate limiting during imports?

Yes, the provided migration scripts include built-in delays and batching logic to ensure your import process stays within Clerk's API rate limits.

Which platforms can I migrate from using this skill?

This skill provides specific guides and scripts for migrating from Auth0, Firebase Auth, Supabase Auth, and NextAuth.js, but the logic can be adapted for custom authentication solutions.
