Hi folks. Need help in doing the following, but first want to check and see if it is feasible with the latest Release, or if I'm just going to be spinning my wheels on this one. The Objective. ============= I have a FreeBSD 4.9-RELEASE system which I want to upgrade to 7.X from the source level. Had a bunch of problems installing 7.1-RELEASE from the CD distribution I got from freebsdmall.com. Several problems that could not mount the CD at the time of installation causing sysinstall to halt. So, 4.9 is installed and working, is there a source level backward compatibility issue between 7.x and anything older than 6.0 ? In other words, upgrading from the sources with such an old distribution is a doable task ? Your response is greatly appreciated. Many thanks. --Rom a_romolo at hotmail (dot) com _________________________________________________________________ Ready for Fall shows?

But I didnt do some cross compile from 4 to 7, too much like hard work that! So quite possible to upgrade without repartitioning disc & reloading data. But you might want a bigger root. You might want a newer FFS for performance (can't remember when that came in). ... there'll doubtless be a few other `Gotchas' so if you have problems/ not enough experience/ get stuck. the safe way is a back up, & reinstall. Well, a back up's not exactly a foolish precaution anyway ;-) Good luck.

Is it worth trying to do in multiple steps? Maybe not: you'll almost certainly want a larger root partition, and may very well want to change to UFS2, both of which mean that you're going to have to dump to backup, repartition, reformat and restore at some stage (and that stage is one of the intermediate stops, because you don't have UFS2 in 4.9). So: you're going to need to be able to boot from the 7.2 (or whatever) kernel+fixit combination to do the reformat anyway, so why not go the whole hog and reinstall directly to 7.2 (or so) at the same time? That's what I did when I hit the UFS2 barrier, and I'm otherwise a died-in-the-wool source upgrader. If you're having trouble getting 7.1 to boot from CD, then try 7.2 or otherwise sort out that problem, because not having a bootable CD fallback position is not a comfortable place to be, anyway.
