Focus area 04
Modernize established systems with respect.
I help understand, secure and gradually evolve OS/2, mainframe and other established software environments.
No big bang – clear steps
Established systems contain valuable knowledge. I first identify what should be preserved, isolated, documented or replaced.
Assessment
Dependencies, data formats, interfaces and operational knowledge become visible.
Protection
Risks are prioritized and critical processes are documented.
Migration
New components can be introduced through clear interfaces while proven parts continue to run.
Platform experience
The documented experience includes DOS, OS/2 Warp, ArcaOS, eComStation, MVS, z/OS, COBOL, REXX, OpenWatcom, GCC, OpenCOBOL and Free Pascal.
