Abstract
A method, system and program product for sizing a programming effort associated with the migration of a computer program from a first to a second computer platform is described herein. The size of a computer program is estimated and an adjustment factor is applied to represent a base estimate of the programming effort required for the migration. Analysis of availability of required middleware, object and program libraries may further lead to modification of the estimate. An evaluation of scaling issues related to the migration and a comparison of the programming models for the first and second computer platform may additionally affect the estimate. If the migration port is to be made from a multiple system platform to a single system platform the re-architecting effort to reduce path lengths such as replacing network interfaces with direct file sharing must be added to the base estimate.
