Well, you can try. You might get errors from DDL syntax the older server
doesn't understand, but usually that won't happen if the dump is taken
from a server of that vintage or older. We don't promise anything, but
I'd expect it to usually work.
I'm a little suspicious of the OP's claim that there were only warnings
and not errors while trying to restore the dump -- an error would go a
long way towards explaining the report. In any case, we'd need to see
all those warnings to have much chance of diagnosing this.
