If your system has files that must be saved, perform a backup before enabling the Trusted Extensions software. The safest way to back up files is to do a level 0 dump. If you do not have a backup procedure in place, see the administrator's guide to your current operating system for instructions.
If you are migrating from a Trusted Solaris 8 release, you can restore your data only if the Trusted Extensions labels are identical to the Trusted Solaris 8 labels. Because Trusted Extensions does not create multilevel directories, each file and directory on backup media is restored to a zone whose label is identical to the file label in the backup. Backup must be completed before you reboot the system with Trusted Extensions enabled.
