AFAIK there are serveral ways of doing this:
- go through the exported data and rename the fields. But that needs some programming
- if you have the old schema and new schema avail what you could do is to
a) import first
b) export the metadata only
c) rename the columns accordingly
d) reimport the metadata
- do it on DB level using some SQL
I'd think if you don't like to go for programming/scripting or SQL the second option is the easiest as it's using built in capabilities.
