My set up is a MacPro running 10.6.3 server with only one hard drive. I will be getting the MacPro RAID card tomorrow along with 3 additional 1.5 TB drives. The situation is that I will turn those 3 new drives into RAID5, and will move all users data to this array. The Mac OS X data shall remain in the old drive. My problem is that I have never been migrate all users data before. My idea would be using "rsync" to synchronize all users' home directory to the new RAID array, and will re-point the users' home directory to use the new RAID array using "Workgroup Manager" utility in 10.6 server. However, I am not sure if 'rsync' would preserves all the permission of home directory. Also, reconfiguring the home dir in "workgroup manager" seems to be tidious work. Do you have any other recommendations for me about this situation?
