To support Unicode + HANA Migration to Cloud in 1 step

Dear Experts,

I would like to confirm and check with all of you, if 1 step conversion to HANA is possible using DMO in below scenario:

1. The source ECC version is Non-Unicode (Source are ECC6 EHP7 NUC & ECC6 EHP6 NUC)
2. We have to migrate from Source-Oracle12 to Target-HANA 2.0 DB
3. Perform On-premise to Cloud Migration

Questions:

1. can SUM1 support Unicode + HANA Migration to Cloud in 1 step (where Source are ECC6 EHP7 NUC & ECC6 EHP6 NUC) ?
2. Are there any challenges of doing Unicode + HANA Conversion in single step?, or shall we keep it in 2 step (first Unicode conversion on-premise & then DMO HANA Migration to Cloud)

3. Can we leverage nZDT in above process using SUM1 ?

Pls suggest and share some insights, will be grateful.

Thanks
