Live Upgrade Introduction

Note - This chapter describes Live Upgrade for UFS file systems. For an overview of migrating a UFS file system to a ZFS root pool or creating and installing a ZFS root pool, see Chapter 10, Live Upgrade and ZFS (Overview).

Live Upgrade provides a method of upgrading a system while the system continues to operate. While your current boot environment is running, you can duplicate the boot environment, then upgrade the duplicate. Or, rather than upgrading, you can install a flash archive on a boot environment. The original system configuration remains fully functional and unaffected by the upgrade or installation of an archive. When you are ready, you can activate the new boot environment by rebooting the system. If a failure occurs, you can quickly revert to the original boot environment with a simple reboot. This switch eliminates the normal downtime of the test and evaluation process.

Live Upgrade enables you to duplicate a boot environment without affecting the currently running system. You can then do the following:

Tip - You can use the Live Upgrade Pre Flight Check tool to detect system configuration issues that would likely cause a Live Upgrade operation to fail. This tool needs to be run before invoking the lucreate command to create a boot environment. For more information about the Live Upgrade Pre Flight Check tool, see the lupc(1M) man page.

For more information on examples using the Pre Flight Check tool, see Using Pre Flight Checker Tool.

Some understanding of basic system administration is necessary before using Live Upgrade. For background information about system administration tasks such as managing file systems, mounting, booting, and managing swap, see the System Administration Guide: Devices and File Systems.
