BW Upgrade 3.0 to 7.0 ( Data Migration for Prod)
We are doing BW Upgrade from 3.0 to 7.0, I need your suggestions.
We are going to upgrade BW Development, Quality and Production landscape to 7.0 and once technical upgrade is done we will go ahead with Function upgrade.
Now point is, once we done with all developments in Production environment then how we will take Historical data?
We are planning to connect Old BW system (3.X) as Source system to new BW 7.0 and then we are going to pull data.
But as we need to move data from Standard data sources like LO we need downtime for Production environment. Our challenge is to minimize this downtime for production environment.
Does any body having idea about this? I am aware of one IBM toll TDMF for data migration which migrate data from one data base to one data base with hardly 2 hours of downtime , but again for this licensing cost and etc is involved.
Please share your experiences and suggestions.
Thanks in advance.
