[sugarcrm] Supported Versions

SugarCRM regularly retires older versions of the Sugar application in order to be able to focus on delivering higher quality in the latest and upcoming product releases. See below for the list of currently supported versions and their end-of-life (EOL) plan.

End-of-Life Plan

The Sugar EOL plan applies to all On-Site versions and editions of the Sugar application, Sugar mobile solutions, and the Sugar Plug-ins, connectors, and extensions. Currently, only the latest released versions of the Sugar Connector for Marketo, Sugar mobile solutions, and the Sugar plug-ins for Microsoft Outlook, Word, Excel, and IBM Notes are supported.
After the EOL dates below have passed, SugarCRM will no longer provide customer support, maintenance patches, or bug fixes for the listed versions. All available upgrade and maintenance patches available at the time of the end-of-life date for a given version will remain available for download but no additional packages will be produced from that point forward.

Version	End-of-Life Date
Sugar 6.5.x	12 months from the GA release of 7.7.0.0
Sugar 7.5.x	March 30, 2016
Sugar 7.6.x	9 months from the GA release of 7.7.0.0
Sugar Mobile Plus	12 months from the GA release of 7.7.0.0

Versions earlier than 6.5 are no longer supported. Please visit this page regularly for updates.

Upgrading to Supported Versions

To upgrade to the latest supported version, find upgrade packages on SourceForge if you use Community Edition or Download Manager for all other editions. After downloading the appropriate upgrade files, upload and install them using the Upgrade Wizard in the Administration page in your Sugar instance. The most current versions of the Sugar plug-ins and extensions can also be found within the Download Manager.
If you run into any issues with upgrading your commercial edition of Sugar, you can contact SugarCRM Support team by submitting a new case within the Case Tracker.
