How can i update teamspeak 3 server to latest one?

question as in the subject, the current server is 3.0.10.3 while the latest one as of now is 3.0.11.4

Well...  Not that I know if this is actually the proper way or not, but it is what I have been using for the last decade.

After I stop the server, I backup my ts3 folder. 
Then download the new server files from teamspeak.com and just copy them over the current files.
Next I start Teamspeak 3
done.
