Dear Martin, I agree with you. I am anxious to upgrade. But I am afraid of losing some data on my only one system. I do not have enough backup.
I am planning to buy a backup laptop before venturing to upgrade. But if there is any possibility of upgrading without losing my documents/data, I would gladly go with that. Please let me know whether it is possible. Many thanks for your time.
