SSIS Error: Cannot Convert Between Unicode and Non-Unicode Data Types

Hellooo out there! Welcome back to (the not quite monthly) SQL Something!

This month we are looking at a conversion error I ran into when trying to alter an old SSIS package:

Fig. 1: Error!


Fig. 2: Change isn't easy...

Finally an error that's pretty self explanatory! The error says it can't convert from non-Unicode to Unicode, so obviously we need to find some way to make the two the same type. :-)
