A few MB, a few dozen > MB or more? I've recently used this technique to update several boxes from 5.1-ish to 5.3 with good results. I'm behind a 24k modem connection, and I don't recall the cvsup taking more than an hour when I did it right. Note that you will want to make sure that you have not just /usr/src/sys, but also thing like /usr/src/usr.bin, /usr/src/gnu, etc. From the original iso install, my system contained only the former and I had to download more than I should have (via cvsup.) I believe the rest to be on the original distribution iso image, but in my case I just let the download proceed. I had built custom kernels so I thought my /usr/src was complete, but it turns out that you need a lot more to 'buildworld' (duh!) and I only realized this when I started the cvsup (since it slipped by me in reading the handbook.) You should be able to tar up your original /usr/src and start a cvsup and see if you like how it's preceeding (if you have disk space.) I've played all kinds of games taking such tarballs from one machine to another on cdrom, and have had no problems. > Another thing is that there seem to be problems with the avr-tools > my current work depends on.

A 'buildworld' will upgrade more than the 'kernel only' (system compiler, system utilities, etc), but will _not_ upgrade things from the ports collection. Nor will a cvsup of 'src-all' update your ports skeleton. iirc, a cvsup of 'ports-all' tends to take longer than one of 'src-all' (when done logically as per my above notes) but it's certainly dependant on the history of what you start out with. I did not notice any of my applications from pre-buildworld not working after the upgrade, but I pretty much set to the task of rebuilding a lot of them right way (after a separate upgrade of my ports tree) so I didn't put much time into testing this. You would want to read /usr/src/UPDATING to try to spot any potential gotcha's that you might tip you over with respect to running earlier software that might be important to you. BTW, you probably know this, but there are a few things to read up on and think about (i.e., mergemaster -p, mergemaster, backups, etc.) Again, I had great luck with the procedures, but it did take some thinking about and some time, and a few mis-steps. I'd mainly re-installed from scratch as a means of upgrading prior to this. I hope this helps. Hopefully someone took better notes of the size questions you have.
