any problem going from 9.x (don't laugh) to 11 directly?

Oh, another way I've done this in inside VMs.  Once configured and built
to my satisfaction, I just tarball off the entire contents of the VM's filesystem.
Then, I pour it onto a bare "real" drive that's been partitioned and formatted
appropriately.

On Linux systems, I do some this with docker instances, although full OS imaging
is a good use case for this approach.
