We passed that two times with two different clients in last year and =
after a week o two of fighting with the carriers choosed to do it =
ourselves to avoid problems.
That was not the best solution due to the time consuming it is, but due =
to our situation was the less painful way.

As a bit of assistance why cant the old ISPs addresses be assigned to
you personally and the new ISP start announcing them. Keep the two
running for a week or so concurrently and nothing address wise should
have to change apart from maybe a could of entries for routers and DNS.

But give this some consideration.... if the rest of us have to download
your message, possibly you'd consider the courtesy of presenting it in a
manner that we may all benefit. Or,... alternatively, send it to
Alejandro privately.
