Can I use this for self-hosted PostHog migrations?

Yes, the skill is designed to handle migrations to and from PostHog Cloud, as well as version upgrades for self-hosted instances using kubectl and npm tools.

What happens if the migration fails midway?

The skill provides a predefined rollback plan, including feature flag deactivation and data restoration scripts, to immediately return to the stable legacy state.

What is the Strangler Fig pattern used in this skill?

The Strangler Fig pattern is a migration strategy where a new system gradually replaces an old one by routing specific traffic to the new implementation until the legacy system can be safely decommissioned.

How does the skill ensure data wasn't lost during migration?

It includes a dedicated validation phase that checks data counts, API functionality, performance baselines, and error rates to ensure parity between systems.
