The user interface transformed to a modern graphical user interface. The application code transformed to a new, object-oriented, programming language.
There are limited options that provide the changes needed, and some present considerable risk and cost elements that may not be acceptable.
For example, if you can find a 'commercial, off the shelf' (COTS) package that is affordable and practical to implement then this option should be seriously considered. However, strategically important mission critical applications, by their very nature are tailored to the unique requirements of an organization and therefore cannot be replaced by standardized packaged solutions without extensive customization. Packaged solutions often require major shifts in how the organizational processes flow which can increase the implementation costs significantly.
Or, you may re-write the legacy application in a modern development language using new tools. Although this may initially appear to be an attractive option, the scope of such a project cannot be underestimated. Projects to reengineer decades of legacy information systems will take years to complete, require hundreds of man-years of effort at a huge cost and risk to the organization. The IT landscape is littered with failed attempts to undertake projects of this magnitude.
Or, you can adopt the Inglenet "soft landing"
approach. Our approach is to liberate the system from legacy
technology restrictions while reducing the variables. By taking
a phased approach we reduce risk and focus on achieving specific
