Hi Rummy,
Thanks for your message.
You can perform the below to remove Java 9 and keep your data, without requiring any changes to the database.
1) Take a backup of your database
2) Check Burp Enterprise is running the latest version (Currently v2022.6 in Settings > Updates)
3) Download the matching version installer: e.g
v2022.64) Run the installer (right click and run as administrator for Windows, or run using sudo for Linux).
5) Please check and make sure to specify the existing installation directory. Unless you changed this, the default is:
Windows:
C:\Program Files\burpsuite_enterprise
Linux:
/opt/burpsuite_enterprise
- or -
/usr/local/burp_enterprise
6) The existing installation will be detected and you will see a prompt to overwrite the installation. Select OK.
7) The installation files will be replaced, but your data preserved. This will also remove any old Java 9 directories.
Please let me know if that worked for you?
