Migrating from tomcat to websphere

At the moment, I'm developing a java web application locally(localhost) on Windows, using Tomcat 8.5 .

Unofortunately, I have no developing enviroment, so I have to do everything locally and then deploy to production via .WAR .

The issue is that the production application server (Linux RedHat) is running on websphere, if I generate the .WAR on tomcat, Will I have any problems to run it on WebSphere? Should I change anything in my code or web xml?

My system does nothing fancy, no hibernate, no spring, just a very classic mvc web application.

Thanks in advance
