we are having SonicOS Enhanced 188.8.131.52-14n firmware version.
Can anyone suggest me the stable version to upgrade this firewall.
Upgrade path also i needed
Thank you for visiting SonicWall Community.
The latest stable general release firmware version is 184.108.40.206. You can upgrade to this version. We can upgrade from any lower firmware version to higher version with SonicOS Enhanced.
In your case just to be on safer side as you are on old firmware version, please follow this path. We can do incremental upgrade to any of the versions 6.5.1.x -> 6.5.2.x -> 6.5.3.x -> 220.127.116.11.
Hope this helps.
Here are links to two self-help guides:
In the latter, you'll have to scroll down past the new OS 7 information till you find "Resolution for SonicOS 6.5"
That should get you started.
Due to the SonicWall DoS & XSS Vulnerabilities, You would have to install SonicOS 18.104.22.168-83n Firmware.
