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

Can I scale up to a larger Solr deployment?

SearchStax allows you to upgrade your Solr deployment to a plan that offers more memory and greater disk space. You can also upgrade to a larger or smaller cluster.

This procedure is also appropriate to clients who want to make a minor-version Solr upgrade. Note that a major-version Solr upgrade needs a different procedure.

This procedure takes advantage of the SearchStax backup feature.

Best Practice: A/B Path for Scaling and for Minor-Version Solr Upgrade

To change the size of your deployment, or to make a minor-version Solr upgrade, the best practice is to:

  1. Perform a manual backup of your existing system (deployment A).
  2. Create a new deployment using the desired plan and version of Solr. You must use the same cloud provider as before.
  3. Restore the backup into deployment B.
  4. Validate the behavior of deployment B.
  5. Switch over from A to B.
  6. Delete deployment A.

The backup feature automatically adjusts for changes in the number of cluster nodes.

You will be billed for the number of days that each deployment was active during the month. Running two deployments side-by-side during the transition period results in a small increase in your monthly bill.
