// Function: ProfileNeedsMigration
//
// Synopsis: This function determines if we need to migrate a profile or not.
// Profiles that have the current Profile version format or greater
// are not migrated. Profiles that have an older version format that
// have already been migrated (we look to see if the GUID is missing on
// NT5 or if the Delete Entry exists on Down Level) don't need to
// be migrated.
//
// Arguments: LPCTSTR pszPathToCmp - full path to the CMP file
//
// Returns: BOOL - TRUE if the profile should be migrated or not
//
// History: quintinb Created 11/20/98
