You can upgrade FortiAnalyzer 5.6.0 or later directly to 6.0.5. After upgrade, FortiAnalyzer will rebuild the system database automatically.
If you are upgrading from versions earlier than 5.6.0, you must upgrade to FortiAnalyzer 5.6, then to 6.0.x. We recommend that you upgrade to 5.6.4, the latest version of FortiAnalyzer 5.6.
Upgrade automatically triggers an SQL rebuild post upgrade to v6.0.x which essentially needs to be completed for FortiAnalyzer to function normally. Verify the database rebuild status using
diagnose sql status rebuild-db.
For details about upgrading your FortiAnalyzer, see FortiAnalyzer Upgrade Guide.
