What is the Strangler Fig pattern in this context?

It is a migration strategy where the new PostHog implementation is built alongside the old system, gradually routing more traffic to the new setup until the legacy system can be safely retired.

Does this skill help with data integrity during migration?

Absolutely. It includes automated validation scripts to compare data counts, API functionality, and error rates between the old and new systems before fully switching over.

Can I use this skill for major PostHog version upgrades?

Yes, the skill is specifically designed to handle major version upgrades that involve significant architectural changes, SDK updates, or data schema migrations.

How does the skill handle failed migrations?

It provides a standardized rollback plan, utilizing feature flags and Kubernetes commands to instantly revert traffic to the legacy system if performance spikes or errors are detected.

Executes complex PostHog re-architectures and migrations using the Strangler Fig pattern for seamless data transitions.

This skill provides a comprehensive framework for managing PostHog migrations, major version upgrades, and platform transitions with minimal risk. It leverages the Strangler Fig pattern to ensure zero-downtime migrations by running parallel systems and gradually shifting traffic via feature flags. Developers can automate the assessment of current implementations, generate adapter layers for abstraction, manage batch data transfers, and perform automated post-migration validation to ensure data integrity and performance baseline consistency across environments.
