Stuck in SUM phase READDATA_EXP (EHP8)

Hi there,

I would like to update a EHP6 System (Linux SLES 11 with Oracle 12) to EHP8. So i created an upgrade stack with the Maintenance Planner. I downloaded all files and started SUM. But i cant get past the phase PREP_INPUT_CHECK/READDATA_EXP. SUM wants me to enter the mount points

of the kit "BS2016_SP01_MID"

I downloaded the following files:

51050610_7 SAP ERP 6.0 EHP8 Upgrade Export I 1/3

51050610_8 SAP ERP 6.0 EHP8 Upgrade Export I 2/3

51050610_9 SAP ERP 6.0 EHP8 Upgrade Export I 3/3

51050610_10 SAP ERP 6.0 EHP8 Upgrade Export II 1/3

51050610_11 SAP ERP 6.0 EHP8 Upgrade Export II 2/3

51050610_12 SAP ERP 6.0 EHP8 Upgrade Export II 3/3

51050610_13 SAP ERP 6.0 EHP8 Upgrade Export III 1/2

51050610_14 SAP ERP 6.0 EHP8 Upgrade Export III 2/2

51050610_15 SAP ERP 6.0 EHP8 Upgrade Export IV

I extracted all of them, but no chance. SUM does not recognize them at all. Although there are no useful entries in the logs (SUM/abap/log). I also downloaded the kernel 7.45, which SUM recognized in phase PREP_INPUT_CHECK/EXTRACTKRN_PRE.

Does anybody know what to do to get further?

Thanks in advance

Greetings Stefan
