Yes! And It's very straight forward, since TS6 installs in a completely different folder in comparison to TS3. So there are no issues here, even the register path is completely different.
Any older TeamSpeak 3 version, It'll constantly ask to update, because the checks are hardcoded, even if you delete update.exe or block it, still will check for updates. What you have to do is go to this directory:
On Windows: %WINDIR%/System32/drivers/etc
On Linux: /etc
And find a file called hosts. Open the hosts.file and add these lines:
127.0.0.1 versions.teamspeak.com
127.0.0.1 files.teamspeak-services.com
So now every time TeamSpeak 3 check for updates it will fail, since it will check for the local IP, instead of main domain. Since the server won't be located locally, it will fail the check every time. In case you still want to update TeamSpeak 3, then just delete these lines or download the new client and update it manually. (Keep in mind the latest version of TeamSpeak 3 v. 3.6.2 is only compatible with Windows 7 and beyond and thus It's not compatible with this server)
Note: For systems like Windows XP/Vista it might require access to Safe mode, before any modification in the hosts.file.
How to block updating the client?
How make the popup of update TeamSpeak 3 to not show up anymore...?
Very good server to connect old computers such as Windows XP back and running. Community is very friendly and they are archiving old skins, plugins, soundpacks, wallpapers and pretty much everything related to TeamSpeak 3. TeamSpeak Classic, TeamSpeak 2 and Ventrilo are also an option for you to connect depending of the machine you are on.
So in resume It's the only server where you can connect with ease in pretty much any old machine and phone out there :)
