Hi
Thanks for your reply
Yes 1.6is still my previous domaine.
I put a redirection so for the moment BO is not accessible, I can remove the redirection if necessary, by the way the 1.6 data base is available
One more information, in order to recover the order I copy the table order from 1.6 database to 1.7database and renamd it with the good prefixe and it works. In order to recover also the invoices and the order details I try to do the same think for the other table but the columm inside the table are not the same between the 2 versions of database so I didn't took the risk to use the same method.
regards
Cédric
