Replace the FortiManager device

If the FortiAnalyzer feature set is enabled and you need to move logs to a new FortiManager device, use log aggregation. See https://cookbook.fortinet.com/fortianalyzer-log-data-migration-old-new-fortianalyzer/. If the FortiManager being replaced is the primary, after replacing it, use execute fgfm reclaim-dev-tunnel to force FortiGates to connect to the new FortiManager.
