These days, I decided to migrate my Arch Linux from 32-bit to 64-bit. There are several reasons that make me to make such decision.

Firstly, in Arch Linux official site, there was an announcement that Arch Linux will drop 32-bit. And in the wiki page, it mentioned that Arch Linux user should use 64-bit if the processor supports.

Secondly, new distros such as KaOS and Evolve OS only support one architecture 64-bit. That means 32-bit is considered less targeted.
