You can upgrade from vRealize Log Insight 8.0 to 8.1, where both versions are on Photon operating systems. You can also upgrade directly from vRealize Log Insight 4.8 on an SLES operating system to vRealize Log Insight 8.1 on a Photon operating system.

Upgrading from vRealize Log Insight 8.0 to 8.1

The upgrade from vRealize Log Insight 8.0 to 8.1 does not change the architecture of the virtual machine of the vRealize Log Insight virtual appliance. The only change is in the currently booted root partition, for example, from SDA4 to SDA3, which has no impact on the user experience.

If the upgrade to vRealize Log Insight 8.1 fails, an automated rollback does not happen. However, you can do a manual rollback to revert to an earlier version. For more information, see https://kb.vmware.com/s/article/75150. There is no change in the user interface or REST API. When you connect to the vRealize Log Insight 8.1 virtual machine from the command line and work on it, you see systemd-based information, as Photon is based on systemd.
