Can I sequence my old NT4 app’s!?

Well the answer is easy ..... No!? Or is it..... This is really a two fold statement.

We do not have a sequencer for NT 4.0. So basically you cannot sequence your application from NT 4.0 directly and put them straight into your Windows XP SoftGrid environment!


So if that's the case, how do I get my application from NT 4.0 to Sequenced Virtual Application and then deployed? Well, I hate to say it but there is no easy route! The main thing to understand is getting a process behind you to bring your application up to a specific level and then sequenced on a supportable platform such as Windows XP.

Application Compatability 

Application Migration Process from NT 4.0 (High Level)

The above show this process around taking an old NT 4.0 application and passing it through the application compatibility toolkit. Now I am not saying this is the be all and end all but it certainly can be used as a good guide, or flow process you can leverage off!

The Application Compatibility Toolkit (ACT) enables software developers, independent software vendors (ISVs), and IT professionals who work in a corporate environment to determine, before rolling out within the organization, whether their applications are compatible with a new version of the Microsoft® Windows® operating system. ACT also enables such individuals to determine how an update to the new version will impact their applications.
You can use the ACT features to:

  • Verify an application's compatibility with a new version of the Windows operating system, or a Windows Update, including determining your risk assessment.
  • Become involved in the ACT Community, including sharing your risk assessment with other ACT users.
  • Test your Web applications and Web sites for compatibility with new releases and security updates to the Windows® Internet Explorer® Internet browser.

You can download it from here: 

Once your application is to a stable state you can look to run through the sequencing wizards as per normal and capture your application.


The core benefit is that you are just trying to get this one suite of applications working! Not regression testing it against many others 1,2,4,8,16,32,64, etc etc application along side it.

This can help save you and your business valuable time and stop massive amounts of pain with your upgrades from NT 4.0 to XP/Vista! We know that there are many companies still going through these migrations, and in my humble opinion I hope that this helps you migrate more dynamically from these older legacy platforms. (Good luck to the lads up North! You know who you are 🙂 )
