If you need to update your data for analysis, you simply destroy the old FlexClone copy & create a new one - assuming all your 'moving parts' (specific queries, reports, etc.) of BI application are located outside of the actual database.
My issue is they would like it to be as transactionally up to date as possible. that would involve removing and recreating the "snapinfo" drive , then rolling the logs forward. Restore with Standby is what i envisage at the moment.
