You could just load said old preset "as-is", and it will just use 5 of the 10 available bands and configure those 5 bands with the same frequency range and stepping as you're used to. However, I sense you've figured this out and you were wanting to make use of all 10. So, you could double the gain (only gain - not the q or frequency) for each frequency in the original preset like so:
5, 5, 1, 1, -5, -5, 1, 1, 5, 5
...so you're just "plumping up" your original preset (a reasonable similarity of the original preset's curve, rather), and then you can round things off while you're listening to some familiar audio if it doesn't sound they way you think it should.
