Get Data from Table without having the data structure in project.

[leelatoo]

HI,

I have an iOS app versrion 1.0 released in market. There is table named 'XYZ', filled with data (Project contains the data structure of 'XYZ''').
Now working on the next version i.e, 1.1, now i have renamed the table from 'XYZ' to 'ABC' and included a few more columns. The project does not contain the data structure 'XYZ', instead it contains 'ABC'.

When user updates the app, i want to take the data from the table 'XYZ' and fill the data in newly created table 'ABC'.

Can you please help me on this issue?
