I have a laptop supports 64bit. I'm using Ubuntu 12.04 32 bit by a mistake I installed 32bit. Now I want to switch from 32 bit to 64 bit and a new version of Ubuntu 12.10 is also available so I want to install it.

Is there any easy way with out New Installation ?

I have a separate partition for Ubuntu of 40 Gb size if I reinstall the new 64 bit version on it will it remove my applications and other stuff from the other partitions. Like /home partition and /data partition.

Also tell how to make backup.

As far as I know there is no way by which you can convert a 32-Bit Ubuntu into 64-Bit without reinstalling the whole new 64-Bit operating system.

And there is no harm in using 32-bit Ubuntu unless you have more than 4Gb of RAM and you want to use maximum of it.

And if you really want to use 64-Bit then backup all your data and format your current 32-Bit version and install 64-Bit version.
