What should be upgraded first in Advanced Upgrade Method?

The correct answer isC. In an Advanced Upgrade or Management High Availability upgrade sequence, thePrimary Security Management Servermust be upgraded first. The Primary Management Server is the authoritative management database source and controls the rest of the Check Point environment. After the Primary server is upgraded and verified, the Secondary Management Server, dedicated Log Servers, SmartEvent Servers, and finally Security Gateways can be upgraded according to the supported upgrade path. Option A is wrong because Dedicated Log Servers depend on the management environment and are not upgraded before the Primary Management Server. Option B is wrong because a Secondary Management Server must not be upgraded before the Primary. Option D is wrong because gateways are normally upgraded after the management infrastructure is ready to manage the new version. Check Point’s R82 upgrade guidance states that in Management HA, the Primary Security Management Server must be upgraded and running before upgrading other servers.
