How to move NTFS permissions?

W2K, have migrated about 200 Gigs from one volume to another on a file server. Then found out, that filesystem NTFS permissions on files and directories were not copied with the data. I still have old volume with all the data and correct permissionsavailable but some of the data on new volume has allready changed.
I am looking for a program that will allow me to read NTFS file and directory permissions and reaply those permissions to already copied files on a new volume. The data is very sensitive.
Please help!
