[Evolution] Upgrade without losing mail: is there a HOWTO?

[meldav <melissad speakeasy net>]

I am ready to upgrade from SuSE 9.2 to 10.  I have never in the past
been successful at preserving my Evolution inbox, folders, and contacts.

I have been referred to the Archives of this list, but found no means of
searching this volumunious archive.

Is there a HOWTO published?  If not, would someone be so kind as to send
one?
