There are a couple of nice links you should check out on the ARCHIVE storage engine

You may want to think about running OPTIMIZE TABLE on the table before copying it over. I cannot make any promises on an ARCHIVE table be copied to another server. Everybody trusts MyISAM tables to be that portable.

IMHO you are probably better off, definitely safer, doing a mysqldump of the ARCHIVE table and reloading. That way, you could trust mysqld to get the table into a readable, trustworthy format on disk in the new server.
