How to migrate from Classic ASP to ASP.NET

What would you say about a company that aspires to enter the major league of business relying on 25-year-old technology? Today, most people would call it a strange story for an enterprise. And for digitally driven organizations, it is outright ridiculous. Yet, this is symptomatic of some firms today that have ASP-based solutions as a part of their IT environment.  

In the year of its release – and that was back in late 1996 – ASP (short for Active Server Pages) was only an add-on to Microsoft’s Internet Information Services (IIS). It has quickly evolved into a groundbreaking server-side scripting language and engine that was an excellent instrument for web application development. In the rapidly progressing IT landscape, Сlassic ASP steadily lost ground to newer technologies when its creators launched its upgraded version – ASP.NET.

The cut-throat competition in contemporary business leaves legacy ASP product owners no choice but to migrate to Microsoft’s younger brainchild. What are the technical reasons for doing that? 

Benefits of migrating Classic ASP to ASP.NET 

Our experience in providing web app development services allows us to pinpoint the upsides ASP.NET as compared to Classic ASP.  

Now that you know why ASP.NET is better, you can shape your migration strategy, which starts with the preliminary phase.

Pre-migration preparation

There are several essential things you should do before the actual migration begins. 

Migration roadmap 

While implementing data migration projects, we at DICEUS follow a straightforward roadmap that includes five steps.  

Step 1. Devising a detailed plan. This document should contain such information as the scope of migration, clear-cut goals to attain, definite timelines, and resources to.  

Step 2. Determining legacy areas. Here, you should come up with a complete list of systems, web services, microservices, and other elements of the legacy product that require migration. 

Step 3. Backing up data. All user files, databases, configuration settings, etc., must be backed up to provide the integrity of the new product and ensure you won’t lose any relevant information during the transition.  

Step 4. Performing the migration. During Classic ASP to ASP.NET migration, you should start with the data layer and carefully reproduce data-based context and model in the new product. Then, move on to logging, error reporting, caching, and other system functional capabilities. Finally, proceed with implementing controllers and actions in ASP.NET. 

Step 5. Regression testing of the new solution. The final stage is checking and assessing the operation of the migrated product. Our testing team validates its enhanced functionality, cross-platform compatibility, and improved performance. If any element underperforms, they deal with issues they discover. 

Even after the switchover and when your ASP.NET product goes live, there is no time to rest.  

Post-migration routine

The smooth functioning and optimal performance of the new .NET solution are conditioned by the system of measures observed by the IT personnel responsible for its operation. These measures include: 

You must know the pitfalls and bottlenecks while planning and executing the migration and all related procedures.  

Migration challenges to address

What are the most widespread obstacles accompanying migration projects? 

The high-profile skills of DICEUS in the .NET technology and its experience in legacy app modernization can help you overcome all these challenges and perform a seamless migration of your Classic ASP product. Here is how we coped with one of such projects. 

ASP.NET migration: DICEUS expertise

VCA, a pet insurance company from Canada, required our assistance in optimizing its IT environment that contained the core service and several sub-services. The central element of the ecosystem was a hybrid SaaS resource. Some solutions were powered by Classic ASP, whereas others were migrated ASP.NET products. The customer wanted us to implement SSO (Single Sign On) to spare users the necessity of logging in new every time they switched from Classic ASP to .NET products by VCA. 

The major challenge related to SSO optimization is handling sharing session problems. In Classic ASP, sessions resist editing, while in ASP.NET, you can do it by leveraging two techniques. The first consists of saving sessions in the database; the second requires special API tools to access the session. Our team opted for the latter approach and managed to provide SSO for all VCA’s digital landscape components, which enhanced customer experience and streamlined interaction between the organization and its clientele.  

Conclusion

A quarter of a century ago, ASP was an innovative tool in web development. Still, today, it is quickly becoming a legacy technology inadequate for meeting the requirements of the time. That is why switching from Classic ASP to ASP.NET as new-generation know-how with numerous fortes makes perfect sense. 

While performing the transfer, you should carefully prepare the ground for the procedure, adhere to the migration plan, avoid pitfalls that await you along the way, and regularly conduct the necessary follow-up measures. By hiring top-notch IT experts, you will guarantee that the migration process will be smooth and that the new product you obtain provides a satisfying user experience.
