We're currently experiencing issues with Alarm & Audit syncing on our Linux edge devices running 8.1.26. As a temporary measure, we've disabled data sync for alarm and audit, and we plan to roll back to version 8.1.20 before re-enabling it.
To avoid losing alarm and audit logs on the current edge gateway, we need to consider that downgrading on Linux through the installer is not possible. Instead, we must install a fresh version of Ignition. I assume the alarm and journal data are stored on disk, and we could copy the files out and back in after the upgrade.
Is this a viable solution? What are the names of these files and where on disk are they located?
