BPC 10.0 migration to BW 7.4 on HANA

Hi Guru:

We plan to migration our current system, BPC 10.0 SP11 on BW 7.3 to BPC 10.0 on BW 7.4 on HANA will HANABPC addon.

And I have some questions:

a) How the migration work? Can DMO migrate the BW system including the BPC and HANABPC, or it will only migrate the BW, we need to install BPC after the migration, or it could migrate both BW and BPC, we need to install HANABPC?

b) Is there any SP restriction, such as for BPC 10.0 SP11, we must migrate to BW 7.4 SP6?

c) We checked the download center, the BPC 10.0 has different installation package for BW 7.3 and BW 7.4, do the 2 packages have any functionality difference?

Thanks a lot.

Best regards,

Eric
