Obviously take good backups before you try anything.
I recently downgraded one of my machines using sysinstall's binary "upgrade"
feature. Goes something like this:
Download the .iso image for the relase or snapshot you'd like to downgrade to.
(Skip if you already have a CD.)
Use mdconfig to create a device entry for your .iso image. (Skip if you
already have a CD.)
Mount the cd image to /cdrom or /mnt. (Skip if you already have a CD.)
Run /usr/sbin/sysinstall (from your running system, don't boot from a CD).
Go to the options screen and set the Release name to match the .iso image or
CD you're using. e.g. 6.2-RELEASE or 6.2-STABLE-200706.
Go back to the main menu and choose the "Upgrade" option.
Follow the prompts. If you're using a CD then use the CD media option. If
you're using a .iso image use the local directory option and give it the
directory where you mounted the image. Be sure to install the src
Check that the sources in /usr/src match what just got installed and then run
mergemaster to fix up /etc.
These instructions come with no warranty, your mileage may vary, not
responsible for items left in vehicle or data loss, etc etc. Good luck
