Currently we are at BW 7.4 with SP6.0.
Migrated all frontend objects like queries and web templates from version 3x to 7x.
Most of the backend objects like info cubes, ODS and data flow (Transfer rules & Update rules) are still running in 3.x version.
We are about to start HANA implementation in our BW environment.
Since backend objects are still running in 3x version, is this going to impact HANA implementation?
Before HANA implementation is it necessary to migrate all 3x backend objects 7x?
