Does this skill support migration from custom auth solutions?

Yes, while it includes specific templates for major providers, the transformation logic and import patterns can be adapted for any custom database or authentication system.

Are rate limits handled during bulk user imports?

Yes, the provided migration scripts include configurable delays and error handling to ensure compliance with Clerk's API rate limits during large-scale imports.

How does it handle potential downtime during migration?

The skill includes a 'Parallel Running' phase where your application's middleware is configured to recognize both the legacy session and the new Clerk session simultaneously.

Can I migrate users without forcing a password reset?

Since most providers do not allow exporting raw passwords or compatible hashes, this skill provides a strategy for migrating users on their first login or using a phased password reset approach.

What tools does this skill use to perform the migration?

It utilizes Clerk's Backend SDK, the User Import API, and provides TypeScript scripts for data mapping and batch processing.
