If I correctly understood you, then given releases old_v1, new_v2, new_v3
update sequence old_v1 -> new_v3 won't be possible.
This concern also was raised for m2e-wtp <
http://lists.jboss.org/pipermail/jbosstools-dev/2012-August/005793.html>
and as per <https://bugs.eclipse.org/bugs/show_bug.cgi?id=394156> resolved.
So proposal to remove update advise in subsequent release seems incorrect.

And answering your question - yes, plugin ids are also renamed.
