Omari:
9.2.15 is listed in the compatibility guide so that is what is supported. 9.2.18 may or may not work . (Given it is a minor release it is more likely a may.) But if it is not in the compatibility guide, it is not publicly supported as far as I can tell. Marking as answered since two rounds of questions have responses. You are welcome to ask any followup questions
Thanks
