Xen users - Jun 2009 - migration error between different xen versions

Hello, I am a newbie in xen. I got a problem for migration. Could anybody
give me some help? I have two servers: one is with xen 3.1 and the other is
with xen 3.4. I can migrate a vm from the server with xen 3.1 to the one
with xen 3.4. However, when I try the reverse, I got an error like:

Error: /usr/lib/xen/bin/xc_save 38 2 0 0 1 failed
Usage: xm migrate <Domain> <Host>

Migrate a domain to another machine.

Options:

-h, --help           Print this help.
-l, --live           Use live migration.
-p=portnum, --port=portnum
                     Use specified port for migration.
-n=nodenum, --node=nodenum
                     Use specified NUMA node on target.
-s, --ssl            Use ssl connection for migration.

Is it the problem of different versions? I am using Fedora 8. Thank you.

Ming

Yes, the problem is the different versions.  There are years of development
between 3.1 and 3.4

Are there any ways to solve it or I have to upgrade 3.1 to 3.4? Thanks.
