Is it possible to upgrade BW with downtime minimized?
Have you upgraded a BW system using "downtime minimized" (now called standard mode in SUM)?
The reason for the doubt is this note 851449 - "Changeability of BW objects during the upgrade" which makes it sound like data loads could be impacted during the uptime portion of the upgrade. We are upgrading from 7.31 to NW 7.4 and want to use standard (downtime minimized) if that is possible.
The short and sweet answer to you question is yes you can.
Just bear in mind that once you reach step REPACHK your data dictionary/workbench will be locked and you wont be able to make changes in your live (non shadow) instance.
