I've found a description of direct 4.x -> 6.x remote upgrade method (in Russian): http://ark-devil.livejournal.com/2007/02/04/ Here comes a translation: /***************************************************************************** Hail those that make the sunset by hands, ski'd and standing in hammock (c) DE 1. Install a loader of 6.x 2. Install a kernel of 4.x into /boot/kernel 3. Install GENERIC of 6.x into /boot/kernel6 4. Install mfsroot.gz with utilities into /boot/mfsroot.gz 5. echo 'mfsroot_load="YES"' > "/boot/loader.conf" echo 'mfsroot_type="mfs_root"' >> "/boot/loader.conf" echo 'mfsroot_name="/boot/mfsroot"' >> "/boot/loader.conf" 6. echo 'nextboot_enable="YES"' > /boot/nextboot.conf echo 'kernel="kernel6"' >> /boot/nextboot.conf echo 'vfs.root.mountfrom="ufs:md0"' >> /boot/nextboot.conf Now reboot. The loader will try to boot the kernel6 and, if successful, run sshd from mfsroot. You should now log in remotely and perform upgrade as you like. If not successful, the system will boot 4.x after power-cycle and you have another chance. ****************************************************************************/ Eugene Grosbein
