DSX 3 Migration Special, and DSX 4 Concept
DSX 3 was built as a stepping stone. At the time, programming languages and technologies were changing.
But customers had spent good money on systems. We didn't want to see their investments become stale.
So - Version 3 was developed to first, help bridge the gap between old code and new - and finally give us a way of removing old code without losing any customer apps.
DSX 3 Performed 3 Major styles of upgrade path:
- Provided seamless side-by-side Classic ASP and .NET
- Upgraded from Classic ASP & DSX 2 based Web Applications to .NET
- Provided a core runtime library allowing .NET WebForm functionality to be back-ported to large Classic ASP applications - used in a large UK based automotive retailer network to keep an old system on old equipment at least functioning in a modern way. Classic ASP suddenly gained .Net style WebForms!
Whilst Illusionfactor's AccountAbility 2.7 was the only application to be converted and run both DSX 2 and DSX 3 side-by side - it was an important step to prove the process of replacement aging systems - and was developed in the end for free as a demo to the customer
DSX 4 Concept "Playground"
Version 4 never really got used in production. It's purpose was to throw together all the new techiques available on the market to build a test-suite and find out what really worked.
It was our testing ground for lots of new features, compilers, CMS tools and performance trials.
These became the specification for DreamServer 5 Framework
