Thank you for your answer.

Since IB 6 is not developed anymore, I have to migrate my new
programs with FB. However, some of my customers that use my old
programs (with IB6) need also to use my new programs with FB.

Since I support my customers exclusively by e-mail (I never go at
the customer site), I need an easy setup/configuration since my
customers know nothing about computers.

The fact is I did ran both IB and FB on the same port on my computer
and seems to work well. However, since I'm not a guru about it, I
want to be sure that what I have made is correct and I will not get
into any troubles.

So, it's for this reason I asked if I can do that "Without any
problems".

Thanks again for any comments or suggestions. It's very appreciated.
