To minimize the downtime during major version upgrade, blue-green upgrade technique could be the option. Please note, using blue-green upgrade, source cluster should be binary log enabled. To do this, need to engine restart to enable binary log and may cause some performance impact due to additional resource consumption by writing and shipping binaly log.

Another option should be in-place upgrade. You can estimate upgrade time by create cloned cluster and upgrade it for measuring upgrade time.
