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:
- Create a new deployment using the desired version of Solr.
- Configure the new deployment (B) like the previous one (A).
- Load your data into deployment B.
- Validate the behavior of deployment B.
- Switch over from A to B.
- 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.
|Solr Upgrade||Single Node||Cluster|
|Minor upgrade||Best practice: A/B Upgrade
Optional upgrade-in-place. (Extra fee for silver.)
|Best practice: A/B Upgrade
Optional rolling upgrade-in-place. (Extra fee for silver.)
|Major upgrade||Only path: A/B Upgrade||Only path: A/B Upgrade|
