How can i upgrade my LibraCyber ESG installation?
SOLUTION
- Log into your appliance moving to admin area > appliance > system upgrade
- Take snapshot of both nodes (not mandatory, but as a best practice!)
- Press on "play" button on the right side of the page
- A check will show you if all prerequisites are verified and the breaking changes, too
- You can now click on "Execute Upgrade" button
The upgrade should take approximately 10 minutes to complete. External factors like network and storage speed may slow down the process.
Only in a few part of the entire process, mail flow will be temporary paused.
The above guide applies also on cluster environment.
In cluster scenario you can start the upgrade on one node, the other one is automatically managed by the upgrade script.
