How to upgrade a multi-engine installation from v11 to v12

The upgrade of a multi-engine installation may seem like a daunting task, but it is quite easy to do. Here is the procedure to follow:

  • Backup the contents of the directory found at <C:\ProgramData\Acunetix 11>
  • From the Acunetix v11 UI > Settings > Select each Engine and Click on the Delete button
  • Upgrade the Main Installation to v12 by installing v12 on the same machine where v11 was installed. V11 will be upgraded, and all your settings will be retained.
  • Upgrade the Acunetix Engines to v12 by installing v12 over the v11 engine. The v11 engine will be detected, and v12 will automatically install the Acunetix Engine only.
  • After upgrading both the Main Installation and the Engine installations, you will need to configure the engines in the Main installation following the procedure in the "Register Scanning Engine" section.
