All the best,
I think I'll give SLES10 a try. It appears like the migration will be as straight forward as when I moved Zimbra to a new server.
Thanks again for your response.
If you use the software past the evaluation period you are required to purchase at least maintenance.
But you can certainly, legitimately, test SLES/Zimbra absolutely without having to buy a SLES license.
Hope that helps,
