MSSQL6 will have to be down longer than others as it is not syncing well while online. It will be done Saturday night in a timeframe from 10PM till 5am, it may be down even 4-5 hours during this time, we will work to keep it as minimal as possible.
MSSQL7 will be migrated on Saturday night as well, should be between 45 minutes and 1.5 hours down on it.
MSSQL9 will be migrated on Saturday night if all goes well on MSSQL6/7 but otherwise will be done on Sunday night and a similar 45min-1.5 hours timeframe to complete
