Need to migrate users from Windows 7 to Windows 10.


I'm just curious and just need to understand all faisable possibilities. If I have this scenario: Around 1000 users to migrate from Windows 7 to Windows 10.

How long this can take?
What the best tool or way to do that migration?

VERY broad question.  It can take a day or two years or more.  Depends on your resources and how you plan on deploying.  It depends on your users and company geography (100 offices of 10 people?  A single office of 1000 people?  Some combination).  Can you disrupt people?  Is it a 24x7 shop of 9-5 or something else.

If you have the skills and tools, you can script much of the work.  Some businesses prefer a PC refresh than an OS upgrade.  Bottom line, there are many ways and many factors especially in a large organization.  How long it will take YOU depends on so many factors....

The main question here is where you store user data. If you are using roaming profiles then you got a big job ahead of you. If user data is stored locally you got a big job of moving all that. If, however, you are using redirected folders and all user data is stored on a server, then it is pretty easy, really.

At my office, we are in the process of upgrading from Windows 7 to Windows 10 and since we store all user data on a server and they use local profiles, there's nothing to it. Users just login the same way they would on Windows 7 and we make sure their documents folders are pointing to the right place on the network.

Just adding to the good advice given above.....

How much software is installed on these computers?  Is it generally the same on all of them?

How many variations on hardware are there?  Are you sure they all support Windows 10?

If there aren't many different hardware/software combinations, I'd consider creating new installations and imaging them to appropriate hardware.  This assumes, of course, that you have proper licensing to allow this.

If you've not done this before expect some initial time to learn the process.  It's not that difficult and there are many good guides out there.

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

In addition to the above and now three years later, Windows 7 is generally a poor candidate to upgrade now. Old drivers, legacy software, and incompatible hardware. Put together a plan to install Windows 10 on your machines that are two years old or newer, and put together a capital plan to purchase new Windows 10 Machines over the next two years.

Let say the user's profile is local and there are 2 offices. This can take a whole year no?

It depends on how new the machines - 5 year old and older machines may not be able to upgrade BIOS and drivers because manufacturers are not supporting BIOS upgrades on old machines. BIOS upgrades are necessary.

So then if you need to start purchasing machines, it could easily take a year.

If you know what you're doing with scripting and depending on where your data is stored, you could automate this and do it in a week or two (though that's if you're REALLY good).  Or it could take Months or years.  Is your network Gigabit? I'd hope... Are the machines you're deploying to all running SSDs with 8 GB RAM +?  You still haven't said if the users could be interrupted... and how you'll deal with things like migrating email config and documents and favorites and such.

Around 1000 users to migrate from Windows 7 to Windows 10.

as it is a scenario for around 1K users or computers, and you want to reduce your effort and cost as low as possible, a few prerequisites are to be known and highly preferred.

1. are the computers on connected subnets?

2. are the computers in an internal AD domain?

3. is there any system management or at least remote access program in use or deployed?

4. or, as an adminstrator of the 1K users across two offices, what’s your current way to manage them?
