We recommend performing the following tasks to prepare for a successful upgrade of a FortiManager unit. Following is a summary of the preparation tasks and a link to the details for each task.
- If FortiAnalyzer Features are enabled on FortiManager in an HA cluster, you must disable FortiAnalyzer Features before upgrading FortiManager to version 7.4.0. See Disabling FortiAnalyzer Features.
