Hi everyone,  I wish to remove/deactivate the National Accounts(AR) for a client while upgrading from Accpac Ver. 5.2 to Ver. 6.2. There are customers tagged to National accounts and there are also existing transactions too. 

After reading through the forums, I was thinking if the method of creating a new database with the same modules except National Accounts activated will work; Then I will copy the csapp file and the .dct files from the new database created from the database dump to the old database. Finally, I will load the database again. Will this work? I understand that the national accounts fields are integrated with the AR tables.

Can anyone advise how I should proceed with the upgrade with no implication on the data integrity? 

Thank you for any advice!
