A few obvious indicators that shout out that it is time for a migration is the higher lifecycle maintenance costs, slower performance of the application, declining health of the current platform along with technical aging.
Starting from 1993, G&G’s development, modernization, and data integration products, solutions have evolved with IBM as it transitioned from (originally) System-38 to AS400 to iSeries to System i, to IBM i.
Many of the AS400 / IBM i migration and modernization platforms are a bundle of compilers, operating system services, and utilities that enable the migration of AS400 environment along with the databases at the target source level code. This code block is recompiled and executed in the target operating environment such as Windows, UNIX or Linux. These compilers also comprise RPG/400, RPG ILE, COBOL, COBOL ILE, DDS and CL which recompile the AS400 COBOL and RPG source code in the native object code for 64-bit Red hat Linux, AIX, HP-UX for Itanium, Windows Enterprise Server, to name a few.
