What migration scenarios does this skill support?

It supports moving from Langfuse Cloud to self-hosted, self-hosted to Cloud, migrating from LangSmith, and zero-downtime SDK transitions.

Is downtime required during the migration process?

While some scenarios suggest short windows, the skill includes a 'dual-write' strategy that allows for a phased migration with zero downtime.

Does this skill handle data loss prevention?

Yes, it includes validation scripts to compare trace counts and sample data between source and target systems to ensure data integrity.

Can I migrate from LangSmith to Langfuse?

Absolutely; the skill provides a dedicated adapter to map LangSmith runs, spans, and generations to the Langfuse data model automatically.

What technical stack is used for the migration scripts?

The migration scripts are built using TypeScript and the Langfuse SDK, while infrastructure is managed via Docker Compose.
