// 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
