Frequently Asked Questions - SearchStax

The SearchStax® Frequently Asked Questions page includes the following approved question and answer about our Apache Solr Cloud services.

Are Solr upgrades available with SearchStax?

SearchStax allows both minor-release and major-release Solr upgrades to existing deployments.

Best Practice: A/B Upgrade Path

To upgrade to a more recent version of Solr, the best practice is to:

  1. Create a new deployment using the desired version of Solr.
  2. Configure the new deployment (B) like the previous one (A).
  3. Load your data into deployment B.
  4. Validate the behavior of deployment B.
  5. Switch over from A to B.
  6. Delete deployment A.

For minor-version upgrades, it is sometimes possible for SearchStax engineers to perform an upgrade-in-place. There is no charge for Premium deployments (Gold, Platimum, and Platinum Plus levels), but Silver SLA deployments will incur a fee for this service.

For major-version upgrades, the upgrade-in-place option is not possible because the Solr schema changes between versions. This means that index files are not compatible across Solr versions.
