Analysis and Planning During analysis and planning, the second stage of the migration process, the team develops the migration plan. Thorough analysis and planning is crucial to the success of migration. Phased migration requires analysis of the existing application environment, consideration of MPE/iX functionality requirements and dependencies, and careful planning based on migration options available, time and resources required, and desired performance. Analysis The analysis process begins by taking a system-level view of the components to be migrated, and the functionality provided by the new MPE/iX system. The migration project team takes inventory of all applications and databases to be migrated. They must consider how much effort it takes to move each application. The Hewlett-Packard Migration Toolset will be helpful during this stage of the migration process. MPE/iX has been designed as a superset of MPE V/E to provide compatibility between the two systems, but there may be some incompatibilities. Any incompatibilities which may exist in each user-developed application should be identified by running the migration tools. Incompatibility issues may be identified in any of the following areas: * Obsolete MPE V/E commands * Intrinsics * Subsystems * Languages (SPL, in particular) * Privileged Mode applications * Data communications You can estimate the migration effort needed by analyzing how many incompatibilities you find and how many changes are required to work around them. The analysis also determines the migration schedule and strategy you form for each application and database.
