Upgrade means: it will update the core software to new features and better functionality and by doing this update you will never lose any of your personal data, files or installed applications.

Upgrade simply means shifting your home from a Single bed room flat to a Double bed room flat. All your stuff will be there and there is room for some other more but its risky too for arrangement in the new flat.

So There is a chance that you upgrade can fail and it will take the stability of your system or it may be dont want to boot after upgrade , WiFi , VGA drivers , etc many issues are there .

If I were you , What I do ?

• before going to move to the upgrade take all your important data as backup.


• If you more time and high speed Internet , download the ISO of which you would like to get as upgrade and make sure that the hardware and everything running properly in a normal way.

hope that helps.
