See http://wiki.xen.org/wiki/Xen_Version_Compatibility. Normally only N
to N+1 is supported. So 3.4.x->4.0.x was supported and 4.1.x->4.2.x is
supported etc.

3.1.2 to 4.2 represents something like 5 releases, I'm afraid that is
not supported.

Apart from any issue with migration 3.1.2 is ancient (6 years tomorrow!
), I'm afraid it is no longer supported here.
