Regarding the [FGCP multi-version cluster upgrade] feature,
Could you please confirm the following points regarding the behavior when upgrading using [secondary-only] mode?
â– Confirmation
Is it possible to perform multiple, gradual upgrades of only the secondary FW in [secondary-only] mode?
â– Expected Scenario
When upgrading from version 7.4.1 to 7.6.4, the following upgrade path is assumed:
• 7.4.1 → 7.4.3 → 7.6.0 → 7.6.2 → 7.6.4
In this case, considering the possibility of rollback, we would like to keep the primary FW at 7.4.1 for the time being and perform a total of four upgrades of only the secondary FW as described above.
After confirming operation on the secondary machine, we plan to upgrade the primary machine.
