Well according to the code in pg_upgrade.c that message should not be reached when the check option is specified:

if (!user_opts.check)
pg_fatal("There seems to be a postmaster servicing the old cluster.\n"
"Please shutdown that postmaster and try again.\n"); else
*live_check = true;

Can we see the actual command you ran?
