If the old provider is advertising the prefix based on your
advertisement to them (you're running BGP), then their advertisement
should cease shortly after your link to them goes down. Likewise, the
new provider would only propagate the advertisement after you advertise
it to them.

Subject: AS announcement question (easy)
Hi, sorry for this low-level question, but at least I'm not posting in
My company owns a class C, and we're switching ISPs. The "new" provider
telling us that they can start announcing, without us having to tell the
provider to stop announcing. I.e., a 2-3 day period where both are
announcing our class C.
This conflicts with my extremely (admittedly)limited knowledge. Can
let me know if this is OK/not OK?
Thanks in advance,
