Before you update, perform the following steps:
Read the release notes.
Check the package versions that are available from your configured publisher origin. You might need to run the pkg refresh command on the publisher or run the pkgrepo refresh command on the origin location.
Use the pkg update command with the -nv options to display the list of packages that will be updated without actually performing the update.
When you update, use the --be-name or --require-new-be option to make the changes in a new boot environment, not in the current boot environment. For more information, see Boot Environment Options and Boot Environment Policy Image Properties.
