- When the SMS server finds that the client hardware ID has been updated or superseded by another machine and if multiple records are in place having the same hardware ID value for the machine, the older records are marked as obsolete.

Manage Obsolete Clients
If you want to get accurate deployment success rate(%), it’s required to manage obsolete client on daily basis.
What I do normally:
Open SMS Administrator Console-> Expand Site Hierarchy-> Expand Site Settings->Expand Site Manitenance-> Select tasks-> open “Delete obsolete Client Discovery data” properties and enable it.
You need to delete data older than 1 days.
After that click on the “All Systems” collection and check whether any client still shows as obsolete. You can delete those client from the console itself.
Note: During the deployment, package can be targeted to non obsolete clients only.
