1. In Enterprise Console, check which full disk encryption policy is used by the group(s) of computers you want to migrate. In the Groups pane, right-click the group and click View/Edit
Group Policy Details. In the group details dialog box, you can see the policies currently used.
2. Open the Full disk encryption policy you want to disable and deselect all the options under
Volumes to encrypt.
3. Under Power-on Authentication (POA), clear the Enable Power-on Authentication check box. Click Yes in the confirmation message. Click OK.
Make sure the updated policy is applied to the endpoints. (In the computer list, the Policy
compliance status changes to “Awaiting policy transfer”, and then back to “Same as policy” when the updated policy is applied to the computers.)
4. On the endpoint, if tamper protection is enabled, disable it.
Note: You can also disable tamper protection in Enterprise Console for a group or groups of computers. In the respective Tamper Protection Policy, clear the Enable tamper protection check box and make sure that the updated policy is applied to the computers.
5. Make sure that an update is not currently being performed.
a) Check the updating status by right-clicking the Sophos shield in the notification area in the taskbar and ensuring that View updating status is grayed out and cannot be selected. If an update is currently in progress, wait for it to complete before continuing.
b) Open Windows services. Depending on your operating system, click Start > Run and type
“services.msc”, or click Start, type “services.msc” in the Start menu search box, and then press Enter.
c) Right-click on the Sophos AutoUpdate Service and select Stop.
Note: Stopping the Sophos AutoUpdate Service prevents an update from occurring during the uninstallation. If the service is not stopped and the uninstallation of Sophos
SafeGuard is delayed for a period longer than the update interval, then Sophos SafeGuard could be re-installed.
