Infor, Epicor, Aptean, QAD, UNIT4, SAP, Microsoft, Oracle and others all have the challenge of owning many solutions built over 20 years ago or more. In fact, many enterprises are still running twenty-year-old software. Still, many firms have yet to buy their first ERP, and they will certainly not purchase the old ERPs written in RPG, BASIC and ABAP or with Progress databases and so on.
