You can buy a transfer cable which will allow you to transfer saved games and stuff from one xbox to another.
Yes...
You cant, the only thing you can do is transfer the memory to the new xbox 360 slim with a transfer cable.
if you have any xbox 360 before the slim, buy a transfer cable. if it is a slim to slim, on the right side on the vent, there is a hatch that you can open and a thread tag should be visible. then pull the tab out and a small, black, and rectangular hard drive should be there. then put the old hard drive in so the tab is under the hard drive and you can read it with out fliping it. then close the hatch. or you can use a transfer cable for the slim to slim.
Yes. Although you cannot move built-in memory, internal hard drives (like the ones that usually come with the Xbox or can be purchased) and external hard drives such as USB devices allow you to transfer all memory on one Xbox to another. When trying this task, you must find your console settings. Then, from there, your memory. When inside the memory category of your Xbox, choose a specific file or all of your files and either "Move", "Copy", or "Delete" those files.
Go to where you search for connection. The xbox live uses wi-fi for xbox live. if you do not find no connection you need these things. a modem and a router i recommend the netgear connect and play router it works perfect for my xbox slim.
Get a USB, go to your old Xbox, and plug it into one of the two USB ports in the front of the Xbox. Go to "Systems Settings" Under "My Xbox" and click that. Then go to memory, and click Memory Device, then click configure, then go to your Hard Drive, and go to User Profiles, then click on your profile, then click transfer to Memory Unit. Then take your USB, then plug it into one of the USB ports in the back of the Xbox. Then just transfer your Profile from the USB to the Hard Drive.
No
As long as you have an internet connection, you can get xbox live on a 360 or a slim.
maybe
25 GB xbox 360 is a slim.
NO, there is another 4-5 years after a console slim down.
