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?

You're going the wrong way! Why do you want to change down to 32bit? – Tom O'Connor Jan 31 '11 at 9:36
You can still run 32-bit binaries on 64-bit provided the 32bit libraries are installed. – Matt Jul 8 '12 at 23:25

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.
