I am doing source to target upgrade (AX2009 to AX 2012 R3).
In my scenario i had three tables in source AX 2009. T1(user created table), T2(User created table) & T3(Statndard with customization).
T1 contains Emplid, inventdimID, Address & Dimension fields
T2 does not contains Emplid, inventdimID, Address & Dimension fields
T3 I added Emplid, Dimension, Address & InventDimId fields
I need to write Target Data Upgrade scripts for all the tables.
