Hi experts,
Recently, I have been planning an upgrade from R81.10 to R82 for a customer. Since this is my first time performing a Maestro upgrade, I collected system backup files from the production environment and attempted to simulate the upgrade process in a lab environment.
The MHO restore process was successful, but I encountered issues when restoring the Security Gateways (SGs).
After restoring the MHO and adding new SGMs to an SG, the SGMs were able to join successfully. However, they did not receive topology-related configurations (e.g., no management port assignment and therefore no IP address).
To proceed with the restoration, I attempted to use the MHO to transfer the system backup files and Jumbo Hotfix packages to the SGMs and perform a restore. However, when trying to install the Jumbo Hotfix, the system displayed the following warning:
“You are trying to install a package before the First Time Wizard is completed. This can cause the machine to become unstable.”
I am not sure if this is related, but after the restore process, I was unable to log in to the SGM via console.
Additionally, I would like to ask:
If something goes wrong during the upgrade and all SGMs become unavailable, would it still be possible to restore them using system backup, or would a full rebuild be required?
I would greatly appreciate any guidance or shared experience on this topic. Thank you very much.
