Portal upgrade from 7.01 SPS 15 to 7.4 along with UCES 6.04

Hi experts,

Currently, we have UCES 6.04 business package deployed on portal 7.0 EHP1 SPS 15. We are planning to upgrade only portal version and not UCES version. The target portal version will be 7.4

I need to confirm whether UCES 6.04 is supported by NetWeaver portal 7.4?

Thanks,

Ankeet Bhandari!
