Multi-Step Upgrade Procedure
The multi-step upgrade procedure involves upgrading the switch multiple times in order to get from
the source software image version to the destination software image version. EPICenter performs the
upgrade procedure for each iterative step along the way.
Each time you iteratively upgrade the device during a multi-step upgrade, you should perform the
following tasks:
• Back up the current device configuration.
• Perform the current upgrade.
• Reboot the device.
• Restore the device configuration (software image upgrade, only).
• Reboot the device (software image upgrade, only).
• Synchronize the device and the EPICenter database.
For information on synchronizing the device and the database, see Chapter 4.
NOTE
When the device reboots, the EPICenter server waits until the device reboot is complete and the device
loads its configuration file. If the EPICenter server times out while the device is rebooting, it is possible
that the device reboot time is longer than what the server will waits before timing out.
Obtaining the Image and BootROM Versions
Before you perform a multi-step upgrade, make sure that you have all of the required image and
BootROM versions available on your EPICenter client machine. To get the image and BootROM
versions, use the Live Update feature, as described in "Performing a Live Software Update" on
page 183.
Specifying the Image and BootROM Versions
When you perform a multi-step upgrade, you must specify each file that you want the switch to use for
each upgrade step using the file
<installdir>/extreme/upgrade.properties
The
upgrade.properties
