Is there a possibility e.g. tool where I could look up which version of UCS Manager is compatible to Ontap 8.2.4 7-Mode
I have already checked the MIT and the answer is always a "Clustered Ontap" and I do not believe in that result.
The IMT does not list any version of UCS Manager that is compatible with 7-mode. This being said, it's not to say it cannot work, it is just not supported.
