SAPUI5 integration with Webdynpro ABAP or Web UI pages in Portal or Standalone

Dear Experts,

I have experience in Webdynpro ABAP and Web UI (CRM). I am learning UI5 and interested to know, how to integrate SAPUI5 applications with WDA applications (Normal or FPM) or Web UI pages.

Also, please guide on how to pass data between these Pages. As passing data between UIBB's within FPM framework or normal WDA application is different and passing data between Web UI pages are different. Is there any Portal way of passing data between all these pages ?

Any Documents/Blogs would also be more helpful.

Thanks and Regards.
