Switching from win xp to win 7

Question

Windows

It is given, computers in the domain. Some users have xp, others have a seven.
Task: quickly and efficiently transfer everyone to the seven.
Additional information: they use Microsoft's profile transfer utility, but Kaspersky, according to admins, slows down the whole process. As a result, one machine takes up to two hours of work. Given that there are about 1500 cars, this is not very fun.
Additionally: each computer has proprietary specialized software and gigabytes of user data installed.
My solution: we put the full image (with Kaspersky and the main software) from a USB flash drive to a computer, user files are copied to network drives.
All this has to be done manually, and even on a test bench it took almost an hour and a half (Windows itself is installed in 10-15 minutes from a flash drive).
The question is, is there any way to speed this up?
Who and how dealt with such problems?

Answer 1

why upgrade to 7?..
Any special requirements for work?..

Answer 2

Create a roaming profile policy.
Then pour the seven, depending on preference.
Politicians can also pour modern software :)

Answer 3

Are gigabytes of user data stored in profiles?
If so, then I'm afraid that little will work out - they all need to be attributed, and then brought ... You can try to delegate some of the settings to users who are able to do this.

Answer 4

Why kaspersky? Without admin rights, and with admin rights too, Essentials is enough.
this time. Secondly, most software is perfectly deployed through GPO / WSUS / SCCM
, user profiles slowly and neatly fit even on drive D, for example, documents, desktop.
