Backing up the configuration of V/VS-VU models

Before you begin, take note of any major changes between the SNS version installed on the V/VS-VU model and on the EVA model. If required, adapt the configuration of the V/VS-VU model before backing it up.

Check the changes to behavior in the new version:

• For SNS 3.11 LTSB: refer to the section Recommendations in the version 3.11 LTSB release notes,
• For SNS 4.3 LTSB: refer to the sections Points to note for updates from a 3.7 LTSB or 3.11 LTSB version and New firewall behavior in the version 4.3 LTSB release notes,
• For the most recent SNS 4.x version: refer to the section New firewall behavior in the version 4 release notes.

Check the compatibility of the Stormshield client applications used (SSO agents, SSL VPN clients and VPN clients) with the new version. If any component is incompatible, these applications will stop functioning correctly. For more information, refer to the Product life cycle guide.

To back up the configuration of the V/VS-VU model:

1. In the V/VS-VU model's web administration interface, go to Configuration > System > Maintenance, Backup tab.
2. Click on Download the configuration backup.
