So I am planning on upgrading my dom0 from 3.0.4 to 3.1.0. I have already done this for the domU's. But I need to know my backout plan if something doesn't go right. I have a simple question.

If I install the 3.1.0 from the tarball, can I still boot the 3.0.4 dom0 kernel with the 3.1.0 Xen tools if needed? I'm not sure of the compatibility. I had to compile my own 3.0.4 kernel because of missing SATA drivers in 2.6.16, but I believe they are in 2.6.18, which Xen 3.1.0 is based on. I'll try and boot the 3.1.0 kernel, but if it fails, can I boot the 3.0.4 kernel even though the xm tools are 3.1.0?
