5. It's more difficult than you think to determine your Effective License Position (ELP)
Manufacturers’ ever-changing licensing rules can make it difficult to determine your ELP. In many cases, you have to go back years for this and review everything carefully at a line-by-line level. For example, are the licensing rules known that applied when a license was purchased? What licensing rights have been built up during the active maintenance of licenses? Which benefits will lapse if the maintenance ends?
When answering these questions, you may find yourself faced by a difficult dilemma: if you can’t work things out, should you ask a manufacturer for help or would it be better to let sleeping dogs lie?
