Converting .max file to .brd file

Hi everyone,

               i just converted my .max fles (10.5 version)  to .brd files to work on the 16.5 version. After i converted my MAX file to BRD file thru orcad layout translator in 16.5 suite, some shapes,connections and vias are missed in that. And some Clines were changed thier nets. how can i get or convert a exact .max file as .brd file.

 Thanks,
