Upgrade Trial SAP BW on HANA 7.4 (SPS 8) to higher SPS (>=9)

Hi SAP CAL-Gurus,

actually, we use a CAL SAP BW on HANA 7.4 (SPS8) - Trial/Developer-Edition hosted by AWS for internal research. Due to the fact, that we face more and more issue/problems (especially the usage of new HANA-Objects like aDSO, etc.), we want to upgrade the system to a higher SPS-Level. Is this generally possible or has anyone gained such experiences?

Thanks in advance!
