SCCM Update 1602 not delivered from CAS to Primary

[reinos]

Hi

i've a CAS and two primary sites. All updated to 1511

Now i tried to install 1602 using "Updates and Servicing" but this stuck while "run prerequisite checker" without any log entries. Restart server or sms_executive did not change anything.

After this i found a Technet article how to edit the CAS-database and remove the 1602 update entry. Did this and after this 1602 was not showing in "Updates and Servicing" anymmore.

Then i copied the 1602-source files from the EasySetupPayloads folder to another location and started setup at CAS. All worked fine and CAS has a new version.

But now - how can i update the both primary sites? Using stetup-files will not work (error - The parent administration site has different version…)

hope anyone can help.

best regards

Reiner
