Determine the downtime schedule and inform all operators of the downtime schedule(database freeze schedule)The downtime can be estimated based on the size of the database to be converted and otherfactors, such as the time to reinstall the new OS version if reusing the same servers and latencybetween nethost and subhost to be configured.In a scenario with a database containing 500K person records, no network latency, re-using thesame servers requiring OS installation, we can calculate a downtime between 4 to 6 hours perserver. For a server experiencing network latency, add two to four hours to this time. For AIXservers, add at least one hour.Note:This estimate does not include getting the micro controllers back online with the server.B. Picture Perfect nethostB.1 Database conversion process1.
