  • Downgrading Sugar Editions

    When a customer wishes to downgrade Sugar editions, the following steps must be taken. When moving from any higher edition to a lower one, we recommend making the transition first on a cloned instance for testing prior to downgrading your production instance.

  • Installing Sugar with an Oracle Database

    The main requirements to configure Sugar using an Oracle Database Server for data storage are the following:

  • Installing and Administering Elasticsearch for Sugar 7

    New technologies have emerged which scale and perform better than classic database (DB) systems for statistical analysis, full text search, and result faceting. Since Sugar 6.5, Elasticsearch (ES) was introduced as an optional system to power the global search functionality. ES capabilities have improved as well as its integration into Sugar. Because it is no longer possible to maintain DB-only fallback scenarios for the more advanced functionality in Sugar, ES is now a required component as of Sugar 7.1.5. Because of this, you can expect more advanced search functionality in upcoming releases.

  • Migrating from Sugar 6.x to 7

    Note: As of release 7.5, most instances can be upgraded from Sugar 6 to 7. This article is for customers who are not interested in upgrading but wish to move their data and customizations from a Sugar 6 instance to a Sugar 7 instance. For information about upgrading, please refer to the Installation and Upgrade Guide specific to the version and edition to which you wish to upgrade.
