What is a product sunset, and what is involved?
Answer: Product sunset is the process of withdrawing the software from the market.
However, existing software users’ support can not be abruptly halted. Thus there is a period of post sunset support where no new features are added but only the major functional problems are fixed to keep the users operational.
This extended support usually lasts for a short period of time after sunset unless some organization steps in to support the users and customers for a fee and converts the support into a support “business.”
