If your maintenance/support contract(s) expire, you will need to request a reinstatement of your maintenance/support contract via your reseller.
If your maintenance/support agreement is due to expire, please contact your selected reseller to ensure your entitlement is updated prior to expiration or refer to the this page for additional information: http://www.symantec.com/business/products/licensing/renewals.jsp
. This will enable us to help you obtain access to the latest product upgrades, product functionality and fixes available under maintenance/support, and also enable you to protect your business environment from unnecessary risk.
If you have lapsed on your renewal and are now post expiration you can purchase a Software Version Upgrade which will incur a higher cost than a maintenance/support renewal but provides a sizable discount off the MSRP.
