I'm going to upgrade pa 5020 *2 and m 500 to 8.1.9 from 7.1.18.
My plan is:
Upgrade 8.0.19 M-500
upgrade 8.0.19 passive
upgrade 8.0.19 active
upgrade 8.1.9 M-500
upgrade 8.1.9 passive
upgrade 8.1.9 active
Log migration for M-500
My concern is when I upgrade M-500, stored log should be remain. Are the logs removed when upgrade panorama device?
And Is it ok to do log migration after 8.1.9 upgrade is finished? How long does it take?(5TB log storage)
logs will not be deleted after a major upgrade
one key thing to keep in mind is that the log database needs to be upgraded also, so after the device comes back online after the reboot, the autocommitmay take a really long time whiole the database is updated. key is not to panic at this time as the process may appear stalled, but interfering could cause issues
What about the log migration? Can I do it after upgrading 8.1?
And could you tell me approx time of restarting after major upgrade?(5020 and 5TB panorama)
Additionally, I'm thinking stop forwarding log from managed devices during upgrade, restart from where I stopped.
I found cmd 'request log-fwd-ctr action start-from-lastack', will it do as I think?
