Recommended Angular version for HTML applications

Hello,

we are using OIM 8.1.2 at the moment which comes with Angular v6 for HTML5 application development. Is it possible to move to a newer version in terms of backwards compatibility (in regard to the OIM Angular Components/Plugins and the Client)? Is there any recommendation for a particular Angular version especially in regard to the upcoming Angular/Composition API Webshop?

Thanks in advance,

best regards
