Installing this version

To update your firewall to SNS version 3.11.30 LTSB, we recommend that you carefully follow the procedure below.

Before starting the update, ensure that you have read the Product life cycle guide and the sections Important information regarding SNS 3.11 LTSB versions and Recommendations.

Checking the compatibility of Stormshield Network client applications

If Stormshield client applications (SSO agents, SSL VPN clients and VPN clients) are used in your architecture, check their compatibility with the version of the SNS firewall that you wish to install. If any component is incompatible, these applications will stop functioning correctly. 

For more information, refer to the Product life cycle guide and the Version release notes of the client applications in question.

Creating a configuration backup

Before upgrading your firewall, we recommend that you back up its current configuration.

If you have enabled Automatic configuration backup on your firewall, ensure that it is available on the configured backup server. If you do not use this feature, we recommend that you enable it.

You can create configuration backup files from the firewall's web administration interface, in System > Maintenance > Backup. For more information, refer to the Backup tab section in the SNS user manual.
