Introduction

Modernize legacy & desktop applications to Web and Cloud, using Wisej.NET.

Existing Windows-based line-of-business applications cannot be turned into browser-based solution easily. Typically, enterprise-scale solutions have been developed over many years with a larger team, they consist of hundreds of screens, and millions of lines of code.

Legacy Technologies

Thanks to Wisej.NET, the following technologies can be brought to the web:

Automated Migration Options	Semi-automated Modernization
Windows Forms (C#, VB.NET) Visual Basic 6 Gupta/Centura SQLWindows Gizmox Visual WebGUI	Visual C++ Windows Presentation Foundation (WPF) Microsoft Access COBOL xBase, Vulcan.NET, X#

Thanks to .NET, Wisej.NET can be used with a number of languages such as C#, VB.NET, Python, X# and others. To realize web-enabling with legacy technologies such as VB6 or Gupta, intermediate steps for code conversion to .NET will be required.

Rewrite or Migrate?

If you decide to keep the application and you have a trigger point to realize a browser-based solution for web/cloud usage, there are two scenarios to consider:

Option	Pro	Cons
Rewrite from scratch	➕ Improve look & code ➕ Work on something new	➖ Takes many years ➖ Very expensive ➖ High risk to fail ➖ Users may not like it
Migrate to the web	➕ Fast, even if complex ➕ Very low risk ➕ Preserve business logic ➕ 80-90% cheaper ➕ Take on entire team ➕ Seamless debugging ➕ Clean solution ➕ UI/UX improvements	➖ Not fully automatic ➖ Needs Wisej.NET
