Windows 10: a migration project not at all like the others

With the notion of “Windows as a Service” Microsoft challenges the way companies to deploy on user computers. The approach is very structuring on the way companies will have to develop their applications.

With AutoPilot, Microsoft offers an approach where the item is delivered directly by the manufacturer to the user and then updated at the time of its commissioning, an approach very directly inspired by the world of smartphones. This function was introduced with Windows 10 1709.

In anticipation of the end of the Windows 7 support set for January 14, many companies have initiated the deployment of Windows 10 on their PC fleet. If the first deployments were carried out on VIP posts, on nomadic posts, very few companies have now completed the installation of the latest Microsoft OS on all their fleets.

“Some small organizations have completed their migration, but large accounts are still migrating,” says Jean-Pierre Bergez, Windows 10 consultant at Capgemini. “The end-of-life date of Windows 7 is not considered blocking. Some companies will sign up for extended support, but others will go for measured risk-taking and will not subscribe to extended support. “

Christophe Free, Director of Offer Windows 10 at Econocom adds: “Between 45% to 50% of our customers’ fleet should have migrated under Windows 10 by the end of 2019. We have many large accounts among our customers and the inertia is larger but we can say that all our customers have committed more or less scale this migration. “

A migration project not quite like the others

French companies will certainly increase the pace of deployments of Windows 10 until the deadline of January 14, 2020, but Jean-Pierre Bergez regrets the approach taken by many CIOs: “The migration from Windows 7 to Windows 10 is often considered a classic OS migration. For us, it should be seen as an opportunity for IT to get closer to the trades. “

The big difference introduced by Microsoft with Windows 10 is the release of 2 major versions per year. This approach called “Windows as a Service” directly calls into question the way companies are used to updating their positions.

Usually, the DSI tested all the applications of the company before making a master and then broadcast it on the stations. This approach involves several months that can not be maintained now, knowing that Microsoft has already updated one to two times its OS at the same time.

Windows 10 introduces a much faster life cycle

Windows 10 introduces a much faster life cycle that will force CIOs to update at a much higher rate than in the past. These will have to reorganize their internal processes and get on track to keep up with this pace.

“The vast majority of the fleet that has been migrated to our customers is in version 1709 or 1803 or earlier, that is to say, the Windows 10 versions of March 2018 or September 2017, when they made their master. Deployment is still ongoing or we must already evolve these positions … “laments Christophe Free.

When home applications are problematic

If, as the figures put forward by Microsoft seem to indicate, the software of the commercial publishers present a risk of incompatibility rather weak with Windows 10, this compatibility is more random with the software programs developed internally by the companies as Christophe indicates it Free: “the problem often comes from applications developed internally by companies, business applications whose operation is often critical for the business activity.  

As a result, the managers of these applications do not want deployment without first validating the operation of their software with a test phase. But with the Continuous Delivery introduced by Windows 10, it will no longer be possible. “

It is often for these critical applications that CIOs take the same precautions in deploying new versions of OS. For Jean-Pierre Bergez, CIOs will have to revisit this approach, get closer to application managers, business managers to assess in a much more refined way how they will be able to update the posts continuously without disrupting the daily lives of employees. trades.

“CIOs will have to change the way they manage risk”

“CIOs will have to change the way they manage risk. Until now, the ISD has been managing an upgrade project every 5 years on average. The approach was to test everything before launching the deployment of the new OS but with Microsoft pushing new versions of Windows 10 very regularly, IT will have to admit that it will not be possible to test everything before the deployment… ” 

DSIs will have to prioritize their applications according to their real criticality for the business and test the new versions of Windows 10 only on the essential applications, then treat the problems that may occur with less critical applications. “This qualitative approach is new and many CIOs are not yet ready to take the step and have not yet taken the measure of this change brought by the concept of Evergreen introduced by Windows 10.”
