No offense Reinoud, but but security style has absolutely nothing to do with whether one has a filer "with UNIX and NT data". Security style only affects the nature of the file-level permissions. Either UNIX or NT files can be stored in any of the three security styles and in fact, often are.
We've found that best practice is to mixed style sparingly (we've never found a true need in our shop for it) and otherwise use UNIX or NT based on where the most permission modification is necessary. If any automated process is running in an area, we try to give it a security style native to that platform.
In fact, we typically use NT style pretty sparingly simply because most of our users don't diddle with permissions, so giving them ACL's is just enough rope to hang themselves - and all their co-workers too! While ACL's are powerful and appear simple to understand from the surface, many admins themselves have difficulty navigating through all the possibilities and often ACL's end up twisted and tortured beyond recognition (and usefulness).
That being said, I have a UNIX style home directory where I store just as many "NT" files as I do "UNIX" ones. Nothing prevents this. Similarly, we've got some "UNIX" data which resides in NT style qtrees.

Dear Jessica,
For the NT security, the both filers must be set to NTFS or MIXED style (qtree option). Because you worked with unix and NT data, it must be MIXED style. There is no need to format your filer, it has it's own file system (WAFL).
Greetings,
Reinoud

I have a filer with UNIX and NT data. I want to move via ndmp to a larger filer. In preparation for the data move I read somewhere that in order for NT data to maintain security permissions, the destination must be NTFS formatted. Is this true, and how do you perform this if the host is a Unix machine but other NT servers are available. Also how would UNIX data fit on an NTFS format. Any help is greatly appreciated.
