[erlang-questions] Add a field to a record

Hello,

I understand that it would be better to use maps if you anticipate adding fields to a record.

But suppose you didn't anticipate and you've been merrily adding data to your db when you discover--- oops! I need another field.

e.g. You have: 
       -record anything, {
            field1,
            field2
          }

      and you discover that you really need:
       -record anything, {
            field1,
            new_field,
            field2
          }

Is there a cunning trick or technique to make the change without losing data?

Thanks,

LRP
