You need fresh install.
AFAIK, kldxref(8) can be runned _after_ booting in single mode.


I use "fresh install" with all system updates(minor & major). I do it because -CURRENT changes too fast.
simple sheme is:
*
* update buildworld buildkernel
* installworld installkernel -DDESTDIR=/path/to/new/place
* etc merging (for example, by etcmerge(1))
* boot fixing
* (optionally) port installing in chroot (or jail) with new system
* reboot
