Add new computer to licence of migrate - where I find informations needed?

Hi.

(I tried to make a question along these lines just before - but have no idea what happen to it when I logged in to post it.)

I am not your original computer wizard so please instruct me as though a child. I do not feel to get enough information from the similar questions answered. It is not enough to tell me I need to know my computer name or to remember the UNITY licence-number. I need to know where from to gather those information needed!!! Where to send it, what is the EXACT procedure? AND I need to know what to do in my specific case.

First - I think I may have named my old laptop the same as the new one. I don’t like to have to remember a lot of names for things - so shoot me. I am told I need to be able to know this information to be able to use UNITY on my new computer. I want to know what to do if the old and new have same name?

I need to know what I should actually really do - add to licence (I am private customer) or migrate from old to this? Is it possible still to add to licence even though the both computers are laptops? (I do not own table computer.)

The old computer still works - but I find it bothersome even to turn it on - lol. It heats up easy, is bit slow and generally annoys with the fact that it can not connect to web via an wire to modem - only wireless. Well to mention a few <<<. I really need to get some information from inside it to do this?

Where do I find my unity licence-number?

Really - where is located the rest of information I need to give - to do what ever is the best solution for me?

(If you speak computer and find my questions stupid - it is NOT my problem - and as result it IS your problem as to how you will treat me answering this. It has been several months when I started about UNITY. Moving from a country to another has taken priority and I do not remember much anything about what I tried to learn about unity before. But now I have new computer and want to get back with unity.)

Additionally - do I need to inform unity somehow about my new location in the world?

Thank You

Your serial number will be on the email you received when you purchase your Pro license. (If you have not got a Pro license, then just activate free on your new machine.)

Also, I believe if you log in to:

https://store.unity3d.com/account/licenses

you’ll see where you have Unity activated, and can return these.
