The vendor should compute the cost of the backport *including* the cost of opportunity, and including the further cost of opportunity involved in encouraging more backports by the mere fact of having done one backport (if the customer believes they can put off upgrading forever then the pressure to backport more and more features will rise). If the value of doing the backport *significantly* exceeds that cost, then, sure, do the backport. The cost of backporting complex features, particularly ones that have wide ramifications, and particularly when the backport is to Solaris 10, with its awful patching mechanisms, is best understood as astronomical. A backport of Zoned NFS server should be considered as in the high 7 $ figure range, if not higher still -- after all, how do you estimate the forgone value of talented engineers working on innovative new features?? Just say no to backports. Pressure the ISVs instead to re-certify their apps. Legacy costs the customer a lot also -- there's enormous, typically unaccounted-for costs in legacy.
