Update the client as usual. (The Client is available to download from the Client Menu at the top of the screen) https://www.tukui.org/download.php?client=win
The drop down menu to toggle between Classic and Retails is the bottom right of the client. See the arrows in the screenshot.
Here is how it will look when one of the WoW versions is selected
Download and update addons as normal for each of the wow versions.
I always recommend backing up your WTF folder - where your profiles/settings for all addons, including ElvUI are stored.
