Once you decide whether or not you want to synchronize your browsing data across devices, you will be taken to a screen that asks you to choose a look for new browsing tabs. Figure 2: The window on the left is running the Chromium version of Edge, while the window on the right is running the existing version of Edge.

This means that you can try out the new browser without having to worry about losing your existing browser.

The main reason I wanted to mention this is to show you that the new version of Edge is installed in parallel with your existing browser it does not replace it. The other thing I want to point out in Figure 2 is that the window on the right is still running the version of Edge that was installed by default with Windows 10, while the window on the left is running the Chromium version of Edge. The other option is to start from scratch, rather than using your existing browser data.

If you look at Figure 2 below, you can see that the new browser asks if you want to start with your data, which gets synced across all of your devices on which Edge is installed.
