- Upgrading to Release 11.0
- Upgrading to a Later Build within Release 11.0
- Downgrading from Release 11.0
- Downgrading to an Earlier Build within Release 11.0
- Auto Cleanup
To upgrade from an earlier 11.0 build to a later 11.0 build on a standalone NetScaler appliance or a high availability pair, you can use the configuration utility or the command line interface. You use the same basic procedure to upgrade either a standalone appliance or each appliance in a high availability pair, although additional considerations apply to upgrading a high availability pair.
save ns config
To avoid losing these updates, create a /var/nsconfig_backup directory, and move the customized files to this directory. That is, move any files that you modified in /etc directory and copied to /nsconfig, by running the following command:
cp /nsconfig/<filename> /var/nsconfig_backup
cp /nsconfig/syslog.conf /var/nsconfig_backup
tar –xvzf build_11.0-61.10_nc.tgz
To install a FIPS appliance, run the installns script with the -F option. To automatically clean up the flash, run the installns script with the -c option.
During the upgrade, you are prompted for an option to load a different configuration.
If the configuration file for the build to which you are upgrading exists in the appliance, you are prompted to load that configuration.

In the following procedure, machine A is the original primary and machine B is the original secondary node, and <targetbuildnumber> is the build number that you are upgrading to within the 10.1 release.
When you do so, machine B becomes the primary node. If machine B does not function as expected, enter the force failover command on the new primary node (machine B) forcing it to again become the secondary node, and contact Citrix Customer Service before proceeding.
On machine A (original primary node)
