Edit October 2025: The dates within this post have shifted. Non-production environments will be updated starting October 14, 2025. We’ve prepared a comprehensive Guidebook to walk you through the testing and upgrade process. Customers may update their production environments through the Enterprise Search Integration. Any environments not updated by January 5, 2026 will be updated by VIP on a rolling basis within the production migration window from January 5 – January 15, 2026.
We’re upgrading all WordPress VIP environments to Elasticsearch 8.18.2 in September 2025. This upgrade is required as Elasticsearch 7 nears End-of-Life status.
Available Now For Local Testing
In preparation for this work, we’ve ensured that there are no incompatibilities in the Enterprise Search codebase; however, we are unable to test every query customization our customers have. We strongly encourage all customers to test their queries with Elasticsearch 8.18.2 by September to prevent potential issues with search queries.
You can begin testing your applications with the latest version of Elasticsearch 8 today using the VIP Local Development Environment. We’ve updated the local development tools to support the new version, allowing your teams to begin validating compatibility and exploring new features ahead of time.
To start testing locally, ensure you have the latest version of VIP-CLI installed and either create a new development environment instance or update an existing one.
Testing the Elasticsearch 8 Production Cluster
We have also deployed an Elasticsearch 8.18.2 cluster on our infrastructure. This cluster will become the default one shortly after the production upgrade is complete.
If you’re enabling Enterprise Search via the Integrations Center (documentation, announcement), you can switch any non-production application to the new cluster for testing.

At this time, a manual re-index (via VIP-CLI) is required after switching clusters. Work on the automated migration tooling is currently underway, allowing customers to transition to Elasticsearch 8 seamlessly at their convenience in the coming weeks.
Production Upgrade Timeline
The upgrade to Elasticsearch 8.18.2 will occur during a scheduled maintenance window in October 2025. We’ll share exact dates and times closer to the deployment.
In mid-September, we will migrate all non-production sites to the Elasticsearch 8 cluster.
Please note: This is a required upgrade. All VIP sites will move to Elasticsearch 8.18.2 on the scheduled date. There will be no option to continue running version 7.17.8 after the upgrade, as Elasticsearch 7 reaches EOL.
What You Need to Do
By September, we recommend:
- Testing your codebase and queries in the VIP Local Development Environment with Elasticsearch 8.18.2.
- Switching to Elasticsearch 8 via Integrations Center in the VIP Dashboard on non-production environments.
- Reviewing the Elasticsearch 8.x breaking changes and migration guide
We’ll continue to provide updates and support leading up to the rollout. If you have any questions, please reach out via your dedicated VIP support channel.
