I'm afraid you need to do `M c' (gnus-group-clear-data [1]) steps for
the relevant groups.  See also (info "(gnus)Changing Servers").

I doubt that this would work.  The numbers are stored in the group
info (see `G E', gnus-group-edit-group, <Group> <Edit> <Info>).  You
probably need to change the numbers there.  I don't know what else is
required.  Maybe some nntp marks related stuff.

Bye, Reiner.

    convention which is not mentioned in its doc string.  (Fixed in
    v5-10.)
