Hi Anders,
please do use v2 only. The other version (v1) is retired still on by mistake and will be removed asap.
SAP hybris Marketing and SAP CRM RDS V2 supports more recent SW versions, e.g. SAP hybris Marketing 1.1 SP6 (1502).
For all details go to the Getting Started Guide offered in the CAL or visit the SAP Service Market Place at http://service.sap.com/public/rds-crm-trial.
Or check out our blog at http://scn.sap.com/community/rds-hybris/blog/2015/02/10/new-trial--sap-hybris-marketing-and-sap-crm-on-hana
Kind regards,
Marita
