This capability is focused on automatically transforming the UNISYS 4GL called MAPPER application source code to JAVA. Any of the MAPPER databases that are used, most likely sequential files, will be transformed to SQL databases on the target platform. The MAPPER 4GL product is only available on the ClearPath OS 2200 platform. A product called MAPPER C is available on the LUW family (LINUX—UNIX—WINDOWS). As part of the migration process, the contents from all databases on the source platform will be unloaded, then reloaded, to the new target SQL platform. This automatic transformation process may be applied to all of the MAPPER & MAPPER C applications available from a source platform. The JAVA code that is generated from the transformation process can be deployed on any Cloud or On-Premise system as target platforms. The only requirement is that the target machine has a current version of a JVM (JAVA Virtual Machine).
