AX 4 to AX 2012 R1 Data upgrade process

Hi All,

I am doing the data upgrade from AX 4 to AX 2012 R1 using Bulk copy process (source-to-target) after the data's are copied i found that few column/data are not updated in the tables currently.

For an instance, while checking the Journal entry form i do not see the voucher details were not updated along with that the ledger account details on the parameters/posting profile form are also not updated.

Currently we are updating through the scripts. Is it to be done this way? or is there something we can do it in the process?

Thanks.
