Hi

I'm trying to upgrade 7.4 to 8.3, but I fail.

On a third slice I have nine gpt partitions. Originally they were =
created under 6.2 with "gpt".  The upgrade from 6.4 to 7.4 runs without =
problems, but now from 7.4 to 8.3 the partitions are not found. I can't =
see them under /dev and gpart list shows curious things, a fifth slice =
in the third and a EBR scheme instead of GPT. =20
I have load the kernel modules geom_part_gtp, geom_part_mbr, =
geom_part_bsd. Is there a save way to install 8.3 or is it dead-end?
