Gateway/FES Hub interoperability

[Andrea_Bosoni]

In my understanding, as a general guideline, hub deployment for the gateway system serves the purpose of decoupling the lifecycle of front-end and back-end components, but a general guideline suggests to keep the gateway/FES at a release >= than the corresponding backend components. Is my understanding correct? Which would be the drawbacks of a Gateway serving a newer Netweaver on backend side? Is there an equivalent note of 1830198 - SAP NW Gateway: Dependencies Between IW_BEP and IW_FND for more recent FES releases?

Thank you Andre, that was quite the information I was looking for. I'm concerned about the impact of one or more backend upgrades on an existing gateway 2.0 hub. So I was looking for a kind of compatibility Matrix between hub and backend components. From your reply I understand that note 1942072 alone cannot provide this information. Could you point me in the right direction? Thanks in advance!
