Can I Upgrade from v2.1 directly to v2.3?

I gotta admit that I am currently running WP 2.1 and have been afraid to upgrade since that version. I seem to recall a bunch of horror stories about upgrading to newer versions of 2.1, or to 2.2 — something about complicated installation, database incompatibility, etc.

I went to the WP site and read about 2.3, and there was nothing indicated about problems with upgrading. Does anyone know if I can upgrade directly to 2.3 from a 2.1 install?
