Upgrade codeunits are a relatively new concept for me, and I am in need of some help :-)
I have a table with the following structure:
1 Primary Key Code(10)
2 DescriptionText30 Text(30)
3 DescriptionText50 Text(50)
Now I want to change field 3 from Text(50) to Code(50). This would be a destructive change in NAV 2017 CU1 and forcing that change would result in the loss of the data contained in that field.
Can I solve this problem with an upgrade codeunit? How do I do that, exactly?
Thanks for your help.
