Notes:
- Review Upgrading a Solr cluster on how to upgrade an existing Solr cluster that was installed using the service installation scripts.
- Rebuilding the Sitecore index after the upgrade is not required but is recommended. Note that it may have some impact on the environment's performance during this process.
- SearchStax support will provide details about the maintenance window and any potential downtime, which will need to be confirmed by them.
- Major-version upgrades require schema modifications. This forces you to reload your data.
- If the new version causes errors in the environment, it is possible to roll back to the previous version.
- Estimated resolution time (SLA): 2 business days.
Limitations, out of scope, and so on:
- Inquiries regarding implementation advice (such as sizing information, installation assistance, upgrade planning).
- If you plan to upgrade to a version that is not compatible according to the Solr compatibility table, this will be considered a customization. In such cases, Sitecore Support will provide support on a best-effort, case-by-case basis, as it falls outside the scope of our standard support.
