Remove the email module from the dual-mode appliance

After email data migration is complete, a hotfix removes the email module from the dual-mode appliance, converting the appliance to a single-mode web protection appliance that can be upgraded to v8.5 with the standard upgrade procedure.

When the hotfix is installed it immediately removes the email module and reboots the appliance. The action cannot be undone.

The hotfix is specific to the V-Series model (V5000 or V10000) and current Forcepoint software version (8.1.0, 8.2.0, 8.3.0). Be sure to download the correct hotfix for your dual-mode appliance and software version.

Hotfix 333 is for V10000 dual-mode only. It removes TRITON AP-EMAIL and its related files. This cannot be undone.
Hotfix 777 is for V5000 dual-mode only. It removes TRITON AP-EMAIL and its related files. This cannot be undone.

To install the hotfix:

Log on to the dual-mode Appliance Manager.
Go to the Administration > Patches / Hotfixes > Hotfixes page.
Enter the hotfix name in the search box at the top of the screen:
```
APP-x.x.x-yyy
```
Where x.x.x is the version of TRITON AP-EMAIL currently running on the dual-mode appliance, and yyy is:
```
333 for V10000
777 for V5000
```
For example: APP-8.1.0-333 for a V10000 dual-mode appliance running TRITON AP-EMAIL v8.1.0.
Click Find. If the hotfix is not found, ensure that the name is entered correctly.
In the pop-up display, click Download to download the hotfix.
If you downloaded the hotfix package to a local directory, you can use the Upload Hotfix Manually button to upload the hotfix.
Click Install to install the hotfix. Installation removes the email module and all associated files. This action cannot be undone. When installation is complete, the appliance restarts automatically to complete the action. The appliance may restart before the Appliance Manager confirms that installation is complete.

After the appliance completes its restart, the web protection module can be prepared for upgrade.
