Former Member

Hi all,

does somebody know if BW 7.5 still supports exiting 3.x data flows.

We are on 7.01 and want to upgrade to 7.5.

There are different messages flying around.

Any hint on that?

Hi Ralf,

If you check BW 7.5 Roadmap, you will see that 3.x no longer supported.

Try going for BW 7.4.

BW7.5 roadmap link for reference.

Hi Vincent, sai p,

thanks for the information. We have decided going to 7.5.

So , last week I have migrated all 3.x flows to 7.x, except for hierarchies.

As we are now on 7.01, no migration option was supported.

Our upgrade will go first on non Hana SQL based system and then we will run the Hana migration.

I couldn't find any information on how to migrate hierarchy data flows. I hope there will be an option on 7.5 before going to HANA.

Is there any option in 7.01  to migrate to 7.x hierarchy flow?

Hi Ralf,

There is no standard way for time being. You can create new datasource for hierarchy in ECC(tcode BW07) and replace that datasource with existing one.

Hi Ralf-Peter

If your BW is on HANA, then it supports only 7.x dataflows, if it is on oracle or other dbs then it still supports 3.5 dataflows.
