What is the right way to replace a old file with a new one?

[toddyce]

A sysadmin uses the following commands to replace myApplication with myApplication.new.

There are two mistakes. What are they? What is a better way to accomplish the task?

user1#host1:~/tmp$ ls -l
total 8
-rwxr-xr-x 2 user1 eng 523 Aug 6 16:45 myApplication
-rwxr-x--- 1 user1 eng 504 Sep 18 15:27 myApplication.new
user1#host1:~/tmp$ mv myApplication myApplication.orig
user1#host1:~/tmp$ mv myApplication.new myApplication
user1#host1:~/tmp$ ls -l
total 8
-rwxr-x--- 1 user1 eng 504 Sep 18 15:27 myApplication
-rwxr-xr-x 2 user1 eng 523 Aug 6 16:45 myApplication.orig
user1#host1:~/tmp$

I don't know any other better ways, could someone give a clue?
