The SunScreen EFS 3.0 CD-ROM includes a program that automatically backs up your SunScreen EFS 1.1 or 2.0 configurations, certificates, and packages to elsewhere in the filesystem in case the upgrade fails. Then the program automatically removes your SunScreen EFS 1.1 or 2.0 software packages and then installs the SunScreen EFS 3.0 software packages. The following procedures describe how to upgrade both locally and remotely administered SunScreen EFS machines.
Before starting the upgrade procedure to SunScreen EFS 3.0, first make a backup of your existing logfiles. The upgrade procedure will remove your existing logfiles and they will be lost if a backup is not performed. Refer to your SunScreen EFS 1.1 or 2.0 documentation for backup procedures, if needed.
To retain configurations and SKIP keys and certificates (including your system's SKIP local identities) between software upgrades, do not remove /etc/opt/SUNWicg.
