I’m seeing a recurring error on my Appserver that
The Execute method of job definition Microsoft.Office.Server.Search.Administration.IndexingScheduleJobDefinition (ID 9f90e7e1-9935-45db-b701-eebc7a8cf960) threw an exception.

This on a SharePoint 2013 on Premise production farm. How do I resolve this issue?
Went further back in the events log and found this:
The synchronization operation of the search component: 1523cd82-7a0a-41b4-8826-49a0c2acac42 associated to the search application: Search Service Application on server: *servername* has failed. The component version is not compatible with the search database: Search_Service_Application_CrawlStoreDB_a2ae40f397ba4923ae9198efd8818e3c on server: *servername*. The possible cause for this failure is The database schema version is less than the minimum backwards compatibility schema version that is supported for this component. To resolve this problem upgrade this database..
I know how to upgrade the content databases via powershell… but how do I upgrade the Search Service Application databases??
