Design for supporting two version of web pages in java page object model

I am working on page object model. Here is the simplified pseudo code for a test

• Go to home page
• Navigate to my account page
• Login
• Do something
• Logout
• Verify something

Right now I have two versions of account page. And I have two classes for it. One for original account page and another new account page. Above mentioned test was written for original account page. What do I do so that I only create new home page (both pages with almost same methods, but with different locators) but can use the existing tests? There will be two version of other pages gradually.
