If you’re not familiar with the new SCCM servicing model, read our New Update and Servicing section of the 1602 upgrade post which explain it all.Similar to SCCM 1606, if you need to make a new SCCM installation, you can’t install SCCM 1610 directly. To summarize, there is a one way sync from AD - You need to change your Discovery Data deletion task settings in Site Maintenance. You may also want to configure the Inactive Client deletion task settings. The time can be changed, and you can also run a report for clients that have not checked in in a long time and manually delete them, or use a powershell script to do this as well. At a minimum it must be longer than the heartbeat frequency of the clients. Note you don't want to set these very short or your client data will be getting deleted due to relatively brief period of inactivity.
The Update Collection Membership activity is used to initiate collection evaluation.Hi everyone Roberto Rodriguez here with a Configuration Manager support tip for you.If you find that your System Center Configuration Manager 2007 (Config Mgr 2007) or System Center 2012 Configuration Manager (Config Mgr 2012) collections are updating slowly or maybe even not updating at all, take a look at your file.It ensures that the membership of a collection is current before other activities are performed on the collection or its members.For the procedure to configure this object, see: Configuring the Update Collection Membership Activity When you use the browse feature to look up a collection name, or enter a collection name manually or from published data, you must set the Collection Value Type property to Name or the activity will fail.
