Date: Thu, 03 Jul 1997 09:25:35 -0700 Organization: Millennium Research Lines: 23 Message-ID: <33BBD27F.681D@cesium.com> NNTP-Posting-Host: sherekan.yamato.com Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Mailer: Mozilla 3.01 (Win95; I) CC: haggis@cesium.com Xref: euryale.cc.adfa.oz.au comp.unix.bsd.freebsd.misc:44003 OK, Don't laugh... I still have FreeBSD 2.0.5 running. My question: How do I upgrade without bringing the system down for a day, backing up all user files, rebuilding and reinstalling on a clean disk, reconfiguring all the servers, and reinstalling the user files? This is the only obvious way I can see for a comprehensive upgrade. Unfortunately, it is NOT an option. I have dozens of users here and in Japan who use the machine daily! Is there any way to upgrade the major system components "in situ" (maybe bringing the system down for an hour or so)? And if there is no comprehensive upgrade script, what are the major components I'd need to upgrade? (Kernel, Named, Sendmail, Popmail, etc.?) Thanks for any help you can give. -- John R.
