To migrate share permissions for migrated folders, first download and install Permcopy.exe, then use the following procedure.
To migrate share permissions by using Permcopy.exe
1. Create identical file shares on the new Windows Server 2003 file server that matches your current Windows NT 4.0 file server structure.
2. Backup the Windows NT 4.0 file server shares and restore the data to the newly created file shares.
3. At the command prompt run Permcopy.exe using the following syntax:
permcopy \\SourceServer SourceShare \\DestinationServer DestinationShare
SourceServer and SourceShare are the server and share names on the source Windows NT 4.0 file server, and DestinationServer and DestinationShare are the names of the destination Windows Server 2003 file server.
4. Repeat step three for all file shares on the server.
PermCopy does not follow the Universal Naming Convention (UNC) standard, in which you specify the server name and share name together: \\ServerName\ShareName. Instead, PermCopy requires that you type a space character between the server name and the share name. If you do not type the space character, then PermCopy displays a syntax summary and does not copy share permissions.
