This question already has an answer here:

Is it possible to upgrade Ubuntu from 11.10 32-bit to 12.10 64-bit (or the latest version out there) without losing any of my data (files, pictures, etc)?

Is it possible to upgrade from 32-bit to 64-bit at all even?

I found this: Upgrade from 12.04 to 12.10 without losing files? but it doesn't state if it's possible to upgrade from 32 to 64. Any help would be nice. Thanks!

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I don't think this is possible. Also I would look if your pc can handle 64 bit. – Thomas15v Apr 7 '13 at 20:50
My laptop can handle 64-bit, yes. When I full installed Ubuntu about 2 years ago, I didn't realize I chose 32-bit until much later. :( I'm still trying to properly learn all this Linux stuff. – Bunnybee Apr 7 '13 at 20:59
I think Thomas is right, you cannot just upgrade. If you have another computer or an external drive, you could copy all your data there then reinstall using 64bit, and finally copy all your data back. That's probably the safest anyway (even if you weren't switching to 64bit.) – Alexis Wilke Apr 7 '13 at 21:01
Oke, but i think you will need to reinstal ubuntu if u want to have the 64 bit version. – Thomas15v Apr 7 '13 at 21:02
Alright, thank you very much! I'll just upgrade to 12.10 32-bit for now, and perhaps do a clean install for 64-bit 13.04 later in the future if I don't install Windows. – Bunnybee Apr 7 '13 at 21:33

It is not possible, at least not with an easy and safe way. A fresh install of Ubuntu 12.10 64bit is the only safe way to have Ubuntu 12.10 64bit installed. Maybe there are some techniques you could try, but it's more likely to cause problems which will result in an unstable system.
