HP e3000 MPE Migration
TRANSPORT Migration Process
In the cases where migration is necessary and a dual source code pool is required, TRANSPORT™ is used either as a “conversion” or “pre-processor” tool. As a conversion tool, TRANSPORT facilitates a complete migration from the HP e3000 platform. TRANSPORT™ is used only once to create a fully translated COBOL source set. After the initial migration, the TRANSPORT™ translator is no longer needed since all future development will be applied to the new source code. However, during the migration process, maintenance of both source sets is usually required.
As a pre-processor, TRANSPORT™ becomes an integral part of the development cycle. As product enhancements are introduced, changes made to the MPE/iX source are simply re-translated via TRANSPORT™ to produce the new source. This is particularly useful if the migrated application is to be used concurrently on different platforms (i.e., NT and Linux/UNIX). Software is prepared for TRANSPORT™ translation only once, after which it can then be seamlessly ported to any TRANSPORT™-supported platform. The original MPE/iX COBOL is maintained, and TRANSPORT™’s speed and accuracy make this methodology an excellent choice.
In a typical TRANSPORT™ migration, programs are copied from the MPE/iX to the target platform. The TRANSPORT™ translator translates the programs, generates the target COBOL, and compiles the object code. Next, the runtime environment is set up by configuring files that describe the system and by selecting runtime options. Then, preliminary testing of the migrated software can begin. Data conversion programs are generated by TRANSPORT™ and data files are migrated. After final testing, the converted software is installed and the “cut-over” to the new system is orchestrated.
TRANSPORT™ provides the total solution for migrating your MPE/iX COBOL applications to the powerful, flexible open platforms of today. TRANSPORT™’s speed and accuracy far outweigh the costly alternatives of rewriting code or purchasing off-the-shelf solutions.
