Virtualbox 32 to 64bit

I am moving from 32bit openSUSE 11.1 to 11.2 64bit. I assume that I can move my existing Virtualbox installation of Windows XP, provided I install the 64bit version of Virtualbox itself?
It’s the PUEL version I’m talking about, not the OSE from the repos.

Well I’ve just installed the 32bit version of Windows 7 on my 64bit 11.2 (with 64bit Virtualbox) on the laptop, so I suppose I’ve answered my own question… Anything else to consider when migrating existing vdi files?
