My business conrims that they do not need the system when we start the upgrade. so i assuem no downtime minimize is required since no one doing any thing in system.
i understand that down time minimized method can be considered when the business needs the system.
since they do not access the system during the upgrade, can i consider single system mode.
what is the impact of single system?
does the total run time changes?
which run time is much faster?
