Upgrade to Nav 2009

Hi,

I just tried to upgrade from nav 5.0 to 6.0 . I took the back up of old Customized database.Then I created a new database in nav6.0 .While restoring the objects from old customized database to new database it shows an error that line 12 is not defined in the Record Link Table . Kindly provide me solution for this problem or give me your own steps to upgrade from 5.0 to 6.0.

Thank you

is it a Native database or SQL Database?

It is a native database only
