The=20 system is running well, but I'd really like to move up to 7. Can it be done= =20 through cvsup from 6.2-STABLE to 7-CURRENT or is it "wiser" to install from= =20 scratch? any upgrade gotchas/procedure ? I searched the web and the only=20 reference I found was: http://people.freebsd.org/~rse/upgrade/freebsd-upgrade-6x-7x.txt which states: "ATTENTION: THIS UPGRADE PROCEDURE MIGHT NOT WORK FOR YOU AS YOUR ENVIRONMENT IS DIFFERENT. ALSO, THIS UPGRADE PROCEDURES MIGHT DESTROY YOUR SYSTEM AND YOU POTENTIALLY MIGHT LOOSE DATA. NO WARRANTY AT ALL. USE IT AT YOUR OWN RISK!" The procedure is far from a regular source upgrade (like the one noted in=20 UPDATING from 5x -> 6x), hence, my doubts. Also, concerning this statement > 7.X is the beginning of the versions specifically designed with > multiprocessing/cores in mind Does this mean that 6.x will perform better on single cpu systems? =2D-=20 Mario Lobo Seguran=E7a de Redes - Desenvolvimento e An=E1lise IPAD - Instituto de Pesquisa e Apoio ao Desenvolvimento Tecnol=F3gico e=20 Cient=EDfico
