What is the same in SCCM 2007?

Some things have remained the same or have changed very little in ConfigMgr compared to SMS 2003:

Discovery, Inventory, Queries and Reporting.

Key terminology such as Sites, Primary Sites, Secondary Sites remains the same.

Services, file names, share names and ConfigMgr-related groups retain the SMS prefix.

Many Status Messages still mention SMS as these could potentially refer to a Child SMS SMS 2003 Site.

Some programmatic elements have not been renamed such as the SMS Provider to avoid potential backwards compatibility issues for those people using WMI scripting.
