The growing challenge of meeting Legacy IT modernization needs faced by CIOs and executives – Overview of the business and technology background of legacy systems and the ways for modernization – Vilmos Vaspal (Freesoft) - Vortrag in englischer Sprache
Customer issues with outdated IT applications
Do you have a portfolio of legacy applications running on a mainframe?
Is your organization running older IBM mainframes? Are you faced with a hardware decision?
Are you having problems finding and retaining qualified mainframe engineers?
Has the maintenance and enhancement of these applications become expensive, difficult, and time-consuming?
Would you like to move to new platforms without losing your large investment in business rules?
Do you want to lower your monthly software license costs, or switch from older platforms to one with better price-performance?
