Uninstalling a patch release or software upgrade
Often a problem occurs because of a known product defect. Once the defect is fixed, you can install a patch release or software upgrade to fix the issue.
When you plan to install a patch release or software upgrade:
Before you start the installation, use the System> config export command to save a copy of your configuration. After the upgrade, you can use the System> config import command to restore your configuration.
Example:
System> config export local 2016_July_20
System> config import local 2016_July_20 network
To upgrade with minimal downtime, you need to obtain a set of temporary VIP and IP addresses to use during the upgrade. Alternatively, you can upgrade without using temporary VIP and IP addresses, but the downtime increases.
