Almost 10 years ago I got my Tech Plus license. Figuring I'd play it
safe, I put the original in a 'safe' place, and have copies of it here
and there. Now, I want to upgrade instead of simply renewing. Two
questions: Is a copy sufficient when I go for the exams? (That
'safe' place remains safe from ever finding it again, I think). Is
the 'Plus' in the Tech Plus, sufficient proof that I have taken and
passed the 5 wpm code?

Thanks.
