Change Slicehost operating system without losing data

Question

I want to change the operating system on a Slicehost VPS. I'd like to do this in the least painful way possible, so I'm trying to figure out a way to do it without building a new slice from scratch using the new OS.

If it matters, I am switching from the 64 bit version of Ubuntu 10.04 to the 32 bit version.

Is there any easy way to do this?

Take a backup. Even if there's a simple way to do this, you don't want to even attempt it without a backup. Personally I'd recommend creating a new slice, migrating your data across and then asking slicehost to either swap the IPs if they're in the same range, or swap the slices over.
