Best way to upgrade windows version

[alitaqvi]

Hi all - we have thousands of systems which is in the process of upgrade and our SCCM Admins are using software center to push these updates. SCCM DP is hosted on corporate network but since users are working from home the updates are going via WAN and failing apart and update process is not successful.

If there is any more easier way to update windows from 1809 to 1909 like usb, iso, copy the task sequence file etc ? any sort of easier way to upgrade these machines for remote users.

Hi @alitaqvi ,

The Update Assistant in the link below may help you update to the latest version of Windows 10:

There are many reasons why the update is failing.

A good way to update is to use pre-cash SCCM task sequence.

It will copy the content of the update task sequence before it starts.

And also will run compat scan on the current OS to confirm if the update will be successfuyll.

One of the best sources that explains it is here: Windows as a Service: Sharing my PreCache and In-Place Upgrade Task Sequences, part 1 – imab.dk 

We have used it with some configurations for our environment and it works quite well, even if the user is at home.

Hi @alitaqvi and @Mr_Trust_A 

While the Windows Update Assistant tool is definitely the easiest way to upgrade a machine using a USB key the drawback is that it can only be used for the latest OS releases. If I understand correctly you want to move to Windows 1903. In this case the Upgrade Assistant will not offer you this version. 

Do you allow your machines to go to Windows Update? If yes you can then try with policy: 

Select the target Feature Update version

More info: 

When you set the target version policy, if you specify a feature update version that is older than your current version or set a value that isn't valid, the device will not receive any feature updates until the policy is updated. When you specify target version policy, feature update deferrals will not be in effect.
