Upgrade to 1709 not detected as required on some computers

[bservet]

Out of my 300 Windows 10 clients about 100 still haven't upgraded to 1709 despite a servicing plan which targets all of them. The old Windows versions are mostly running 1703 and some are still on 1607.

The problem seems to be that no matter which criteria I use in the plan, the number client requiring the upgrade remain much to low:

It's not clear to me why this is happening or how I can fix this. I guess that if the upgrade packages aren't detected as required any servicing plan is bound to fail.

The upgrade has worked for the other clients and WSUS is syncing successfully so I'm currently out of ideas on how to fix this.

Any help on solving this is much appreciated, thanks!

 

 

EDIT: ok, I've checked the updates list in SCCM and I couldn't find the Enterprise 1709 nl-nl update so I guess that it isn't synced by WSUS

EDIT2: Found the upgrade in WSUS, still not clear why it's not showing up in SCCM:

EDIT3:

Although (almost) all installations are using Enterprise edition, WSUS isn't showing a 1709 Enterprise upgrade package?

 

EDIT4: Possible cause found

 

 

EDIT5:

 

Ok, it seems that the upgrades are working now. It turned out that the hardware inventory wasn't always up to date on about 30% of our clients. I increased the MIF size limit to 15MB and the upgrades are being installed right now.
