Needs to be said, 227 is almost final, but true its a beta.
But i have a good and simple solution for you
A) -On your C drive make a new folder called Unreal227, which would basically look like this: C:\Unreal227
B) -Than copy all the content from your C:\Unreal(Gold) and paste it into your C:\Unreal227
C) -Now run patch 227 and just make sure it patches C:\Unreal227
After that you still have your old Unreal, but also a patched 227 copy. Just start using the Unreal227. And if you encounter problems or anything you dont like, than go back to your C:\Unreal and throw the C:\Unreal227 in the recyclebin. If you dont see problems, stick to 227.
That way you can try patch 227 without altering your current Unreal, simple as that
