BW HANA Migration Using SLO

Interested to hear from the brave who have used SLO tools to carry out a BW on anyDB to BW on HANA (possibly upgrade and) migration.

I understand that the SLO toolsets are preferable if there are more than one BW system to consolidate and then move onto HANA.

1. Are there any other use cases? What use cases would warrant the use of SLO over, say DMO?
2. Are the SLO toolset only available to SAP Services?

Thank you in advance for your comments/inputs.

Regards
