BW 7.4 SP5 Supports BI 3.x Data Flow?

Hi Friends,

We are planning to upgrade from BI 7.1 to 7.4 (SP5), We have more then 30+ data flow which are still in 3.x.

Along with technical upgrade, we are going to do functional upgrade too (only for few flows, and rest important flows would on sill on 3.x)

My questions here are

1. Does 7.4 (SP5) definitely runs 3.x data flows without any issue?

2. What's the minimum GUI requirement for 7.4 (SP5).

Request you to kindly help on this.

Thanks in Advance.

Thanks
