own AS number, how much downtime will there be?  So far the second ISP has
only said that it could be hours for BGP to fully converge.  We are looking
for more detail about how long the outage will be and how widespread.

1) Hire someone that has done this before.  There're many things to be aware of.

2) Get a different provider.  Anyone that said it "could be hours for BGP to fully converge" is misleading you.  Especially, if you're a new customer to them.  That's a bad omen for things to come.

This can be done with very minimal impact.
