How to Transfer Data from One Laptop to Another using Crossover Cable

Lots of time my friends asked me how to transfer their data from his one laptop to new one without using flash drives or CD/DVDs or without going to a LAN network. And this remind me to write an article about how to transfer data from old PC/Laptops to new ones.
There are two ways you can transfer your data:
  1. Using ad-hoc wireless network (that uses wireless card).
  2. Using Cross-Over Cable.
As, this article is about Crossover Cable, there are certain steps you need to make sure, setup are configured properly. I will try to go through all the different steps.
Step 1 – Configure IP Addresses
Usually, if you are using a crossover cable to connect two computers, the computers are not connected to a LAN network. In this case, you will need to configure static IP addresses for each computer.
You have to make sure that both computers have IP addresses that are on the same subnet. For example, if you give one computer an IP address of 192.168.0.1, then you should give the second computer an IP of 192.168.0.2. (There can’t be two apartments with same house number in the city)
If you used the above IP addresses, you should use a subnet mask of 255.255.255.0. If you use an incorrect subnet mask, the connection will not work. (Subnet mask is responsible for dividing IP address into network address and host address)
Lastly, the value for the default gateway should be the same on both machines. You can pick which IP address you want to use, but use it on both computers for the default gateway.
Look at the screenshot:


Step 2 –Connect both computers with Crossover Cable
The second thing you need to verify is that you actually have a proper crossover cable. Basically, there are a few different types of crossover cables, but it’s best to get the standard crossover cable where the green and orange pairs are swapped and the brown and blue pairs stay in the same position.
The only pins that need to be crossed are 1,3 and 2,6. So just check your cable on both end and make sure it matches the diagram.

Step 3 – Local User Accounts
If you’re having problems accessing files both ways, you may have to create a user account on each computer that has the same name and same password. This helps get past any kind of Access is Denied errors that may pop up.
Make sure the accounts are administrator accounts also! It’s best to create a new account rather than rename a current account.

Step 4 – Disable Firewalls 
(remember, you are in standalone mode so it’s safe to disable temporarily)
.
Finally, you should disable the firewall on both computers to ensure that none of the file sharing ports are being blocked. You can do this by going to Control Panel and then Windows Firewall. Click on Off.
Now You have done! Be Sure you have followed the steps same as it was written here.
In case, if you would face any problem, write your problem with a screenshot,I will try to reply as early as possible.
