Description
In this article, we will discuss how to upgrade SonicWall Email Security Hardware or Virtual Appliance solution in a Split Mode configuration.
Resolution
NOTE: These procedures stop the background services from running or starting Tomcat only from the Control Center within a Split Mode configuration.
To update the SonicWall Email Security solution:
- Install Putty, a telnet client downloadable from the internet.
- Log into the CLI using Putty.
- Enter the IP address of the Email Security device and the Port number as 22.
- Login as snwlcli.
- Enter the Admin/Password credentials of SonicWall Email Security.
- On the CLI prompt type the following commands:
SNWLCLI>stop appservices
It will take a few minutes to stop services and return to the prompt.
SNWLCLI>start tomcat
End users will have no interruption in accessing their Junkbox while there are no other background Services running.
NOTE: Always upgrade the firmware on the remote Analyzers (RA) first and then the Control Center (CC). If you have a series of upgrades to be done, for example, you want to upgrade from 8.3.2 to 9.0.3 to 9.0.6 and then to 9.1.3, you will have to upgrade your Remote Analyzer from 8.3.2 to 9.0.3, then CC from 8.3.2 to 9.0.3. Once the batch of 9.0.3 is done, go to the next batch 9.0.6. The RA and CC must be done in batches of the same firmware.
- Next, upgrade the Remote Analyzer by following the Procedure to upgrade firmware on SonicWall Email Security Solution
- Reboot the Remote Analyzer.
