Frequently Asked Questions About Upgrading

• Will I be able to use the upgrade option on my system?

  The upgrade option is supported on any system with Solaris 2.4 or later installed. Type the following command to see what version of Solaris software the system is running.

  $ uname -a

• Do I have to back out patches before I use the upgrade option?

  No.

• How do I use the upgrade option with custom JumpStart?

  You must specify install_type upgrade in your profiles.

• What if the Solaris Interactive Installation program doesn't provide the upgrade option, but the system should be upgradable?

  See Chapter 5, Troubleshooting for more details.

• How can I test my profiles that use the upgrade option?

  You can use the pfinstall -D command to test profiles that use the upgrade option. This enables you to see if a profile will do what you want before you use it to upgrade a system. This is especially useful with the new "upgrade with disk space reallocation" feature.

  To test an upgrade profile, you must run pfinstall -D command on the system that you're going to upgrade, because you need to test the profile against the system's disk configuration and its currently installed software. You cannot test an upgrade profile using a disk configuration file. For details, see "Testing a Profile".

• Can I automatically upgrade to another software group?

  No. For example, if you previously installed the end user software group on your system, you cannot use the upgrade option to upgrade to the developer software group. However, you can always add software to the system during the upgrade that is not part of the currently installed software group.

• Where does the installation program log any local modifications that the upgrade couldn't preserve?

  • Before the system reboots: /a/var/sadm/system/data/upgrade_cleanup

  • After system reboots: /var/sadm/system/data/upgrade_cleanup

• Where does the installation program log what happened during the upgrade?

  • Before the system reboots: /a/var/sadm/system/logs/upgrade_log

  • After system reboots: /var/sadm/system/logs/upgrade_log
