info needed-upgrade 8.1 to 10.0 with zfs root

[Gene]

Thanks - in spite of the fact that I've been running a FBSD system since 
around ver 6.0, I am still in many ways a neophyte. I get some of what you 
wrote, but:

if I understand, you're saying basically, do an upgrade to 9.x first and then 
go to 10.0?

What's "stamp bootloaders"? Does that have to do with booting from a zfs root?

My main concern is the root on ZFS. I want to make sure I can boot this puppy 
when all is said and done!

Thanks...
Gene
