Backup WM6.1 threaded SMS chats

[Darkness231]

I am updating from DCD'd 2.1 to 2.2 and have accumulated texts that I would like to keep. I am using the default text messaging application. After loading the new ROM and trying to restore the PIM data, and My documents and email everything is back but the text messages. There is a file called convstore.vol is the main level of the device but restoring that did not help, also restored the windows directory and no help. I'm sure that someone else has run across this already. Any Ideas

EDIT. Trying to do a full restore via Sprite backup states the bellow .vol files could not be restored. Trying to restore with spb backup.
\mxip_initdb.vol
\mxip_lang.vol
\mxip_notify.vol
\mxip_swmgmt.vol
\mxip_system.vol
pim.vol
cemail.vol

I imagine that it within email.vol. but I cannot locate that
