Client component upgrades follow the same requirements as appliance upgrades. The latest hotfixes for the
client components should be applied before the performing the upgrade.
You can upgrade appliance and client components to 12.4.1 as shown below:
12.4 + latest hotfixes > 12.4.1
12.1 + latest hotfixes > 12.4.1
When you are upgrading from SMA 12.3, it is recommended to upgrade to 12.4.0 first, then upgrade to 12.4.1.
After you upload the client hotfix to your appliance, the client-side fixes are then automatically pushed to each
client system as it connects to the appliance. Depending on your environment, this can take a few days, weeks,
or even months before all clients have connected and received the client-side fixes.
To use Central Management Service with Global Traffic Optimizer, Connect Tunnel clients must
upgrade to SMA 12.1 or higher.
