Extended Support Life Cycle

Customers with a valid Product Subscription and who require support beyond the Core Support end-date can sign up for Extended Support. Available for an additional fee, Extended Support lengthens the customer's support window for one or more years beyond the end of life of Core Support.

Customers covered by Extended Support receive critical and security bug fixes for a fixed version of the MontaVista Linux kernel, OS platform, and development tools. Extended Support packages are renewable annually or on a fixed term basis for as long as necessary.

To be eligible for Extended Support, a customer must be a licensed Product Subscription holder, and must sign up prior to the Extended Support "purchase by" date shown in the table above. MontaVista will not sign an Extended Support license with a new customer after the Extended Support "purchase by" date.
