System-Assigned vs. User-Assigned Version Identifiers
CentraSite maintains two version identifiers for a policy: a system-assigned identifier and a user-assigned identifier.
The system-assigned identifier is a version number that
CentraSite maintains for its own internal use.
CentraSite automatically assigns this identifier to a policy when the policy is created. You cannot delete it or modify it. A policy's system-assigned identifier is numeric.
A policy's system-assigned version number is shown in the System Version column on the Run-Time Policies page and in the System Version field of the policy's detail page.
The user-assigned identifier is an optional identifier that you can assign to a distinguish a specific version of a policy. This identifier does not need to be numeric. For example, you might use a value such as "V2.a (beta)" to identify a version.
A policy's user-assigned version number is shown in the Version column on the Run-Time Policies page and in the Version field of the policy's detail page.
