SBC upgrade path from SCZ8.3.0 MR-1 GA to Current and possible solutions
Hi guys,
I have to upgrade to the latest release an 1100 HA pair from 8.3.
Upgrade Plans:
SCZ8.3.0 MR-1 GA --> S-Cz8.3.0m1p15B
S-Cz8.3.0m1p15B --> S-Cz8.4.0p15 (or higher)
S-Cz8.4.0p15 (or higher) --> to S-Cz9.2.0p5
My question is if we can save the config …. make these steps on a VM … then export and import into 1100 (which will be upgraded to the last version) and in this way to avoid many restarts. Make sense ? I guess using warm upgrade the customer will not feel the impact anyway.
Thanks
Adrian
