What would be the right approach to move from BW 7.0 SP27 to BW 7.5 SP3 with existing 3.x data-flows?
When we did a direct upgrade of sandbox from BW 7.0 SP27 to BW7.5 SP3 we have several deactivated / missing transfer rules for 3.x data-flows - especially on the master data dataflows. However someome 3.x dataflows did get activated and working right-away- especially transaction dataflows.
Is upgrading directly from 7.0 SP27 to 7.5 SP3 the right approach or is there a necessity to go via a intermediate 7.0 to 7.3 to 7.5 approach?
Is there a necessity to migrate 3.x dataflows first or at all? For that do we need to be atleast on 7.0 SP32 to get the 'migrate dataflow' option.
Is the SAP_BW_BEFORE_UPGRADE task list using tcode STC01 - a necessity before the upgrade? For that do we need to be atleast on SP31 or implement SAP Note 1734333 before the upgrade?
Being a non-HANA DB and having a lot of 'classic modelling objects' and no SAP 'HANA modelling objects' is it still ok to move to 7.5 SP3 or there is a necessity to convert the modelling objects?
Is it a necessity to go to BW 7.5 to get the Netweaver 7.4 basis component to be at par with rest of the latest versions of ECC, CRM EP Netweaver components?
Thanks in advance for your time BW professionals.
