Bigstack Life Cycle Planning

Bigstack delivers an eight-year life cycle in Full Support and Maintenance Support Phases with an optional 2-year Extended Life Cycle Support. The optional Extended Life Cycle Support (ELS), a yearly subscription for professional and technical services, provides support that extends past the maintenance phase. The following sections outline the support policies and define relevant product milestones.
