I am currently using angular 2.0.0-rc.4. I would like to convert it to 4.1.0. Is 2.0.0-rc.4 compatible with 4.1.0? I read in this document that it is backwards compatible with 2.x.x , Is 2.0.0-rc.4 includes in 2.x.x?
You will need some reorganizing, not big changes for example after 4.0 template is no more available you need to use ng-template instead.For animations you need "@angular/animations": "4.1.0" this package and finally you can import it like this
import {BrowserAnimationsModule} from '@angular/platform-browser/animations'; i guess thats all you need to know at the moment.
There is an Angular upgrade guide App available which I can recommend.
Have a look at AngularUpgradeApp
It' explains for a wide range of fromVersions what to do to get on the required toVersion
