How to convert traditional web to Reactive web app

I want to convert traditional web application in a reactive web application, is there any fastest way for this kind of migration? if yes please let me know?

thank you 



Hi VS,

As  I known you can not convert directly from traditional to the reactive web app, but you can copy all server and client action but you need to rebuild UI in reactive, but you can not copy the whole things one time.

I hope this helps you
