Win7: To Migrate or Not to Migrate?

EddieC 3 Tallied Votes 682 Views Share

With the release of any new OS release, the question facing developers is whether or not to port existing applications. Often the answer hinges on two major factors: Will the operating system be widely adopted and what's downside of doing nothing?

In the enterprise the decision is often made for you, when policy dictates whether the company will upgrade its desktops to something new. According to a survey of 450 developers conducted by Visual Studio Magazine published this month, almost two out of every five (38.9%) are currently developing for Windows 7 or plan to do so within the next three months. That, despite the fact that not all of Win7's promised capabilities will be present in .NET Framework 3.5 Service Pack, which is included with the release. The Multi-Touch UI, ribbon toolbars and other major functionality will have to wait until next year when .NET 4.0 comes out.

While UI whistles and bells are a major focal point of Windows 7, most of the developers surveyed were more interested in better performance. When asked about their "level of excitement about specific Windows 7 features," the top two responses were improved security and optimized I/O handling. Tied for third place were a "power-efficient infrastructure" and an "updated graphics stack and high DPI support."

Will Windows 7 be the must-have OS that XP was, or will it fall flat in the enterprise as Vista did? I'll admit I'm rooting for Microsoft. After all, Apple's OS fortunes certainly turned in the 1990s with System 7, the focus of which was not on look and feel, but on performance and peer-to-peer functionality. Perhaps Microsoft will be as fortuitous when Windows 7 arrives in stores on Oct. 22. The way I see it, Windows 7 is already widely referred to as "Vista fixed," meaning that Vista's coming whether the world wants it or not. So you might as well get to work.

A pragmatic migration guide that complements the discussion by , and : treat “migrate or not” as a prioritized program, not a one‑time decision. Triage applications by business criticality, user count, and technical risk (kernel drivers, installer behavior, 16/32‑bit/COM components). Plan a short list of apps that must be native on Windows 7, a middle tier for remediation, and a small set that can be supported only via containment or virtualization.

  • Inventory everything: collect app, installer and driver details; tag apps by frequency and owner.
  • Run compatibility scans and targeted tests on both 32‑ and 64‑bit images; track results in a central registry.
  • Apply quick fixes first: compatibility shims, installer changes (avoid writing to Program Files or HKLM), and UAC‑aware manifests.
  • Rebuild/retest for x64 where it matters; consider updating third‑party components and redistributing signed drivers.
  • Use virtualization as a temporary containment strategy for rare legacy apps; schedule long‑term remediation for any app in production.

The Microsoft Application Compatibility Toolkit (and the compatibility tooling in the Windows ADK) is the right place to start for automated inventory and shim testing; add UAC and DPI settings via an application manifest so behavior is predictable on Windows 7. (learn.microsoft.com)

As noted, XP Mode (Windows Virtual PC + an XP VHD) can bridge many legacy cases, but it is a compatibility layer with limits (performance, hardware acceleration, edition and licensing restrictions). Treat XP Mode as a stop‑gap for business‑critical legacy apps rather than a permanent substitute for porting. (support.microsoft.com)

Kernel‑mode drivers and any low‑level components require careful attention on 64‑bit Windows (signing and test‑sign workflows are required during development and before deployment). For large deployments, adopt a phased rollout with telemetry, rollback plans, and clear owner/maintenance schedules so end users (and admins) aren’t left with unsupported binaries.

I think it will do much better than Vista. It is a good combination. The only concern would be compatibility to older programs if one can not run the XP Mode.

To be honest, I think the fact that end-users are savvying up should be the point to consider.

When XP was released, some devs took 12mths or more to upgrade their wares, counting on the fact that a slow adoption rate would keep the up-roar to a minimum. With Vista, many users were happy to throw the blame at MS for lack of backwards compatibility, and software vendors were happy to hide behind that excuse... I mean, Vista was already copping a lot of flak, so it was easy to hand off the blame.

In all honesty though, I think end-users are wising up, as many are being better educated as to how a buggy piece of software, or a bad driver, can bring down even the best OS. To be honest, I think if software vendors sit on their lorrels this time round (especially as MS is offering a high-quality OS that makes a large scale transition both viable and attractive), you'll likely find users looking to software alternatives.

I agree with you. With the amount of software available now vendors are not going to be able to drag their feet.
