I discovered this by accident. I had an SP which contained a variable
CURRENT_ROLE which I used in IB6. When I restore in FB1.5, there is no error
or warning, but the SPs using this variable were simply truncated after the
word AS. So I had to then recreate them.
I think you'll have to change the name in 5.6, then upgrade.
