I don't use zfs, but I have made that update on a number of systems. = There can be issues depending on the specific 9.x and if you use = freebsd-update or build from source. FreeBSD 9.1 cannot use = freebsd-update to go directly to 11.x. There are patches required to = freebsd-update to be able to make that work. The patch should be in the = archive. I no longer have any 9.x systems and don't recall if I still = have it. If you going that way, let me know and I will search for it. During the upgrade process when you first reboot, you really need to = boot in single user mode. I have always done a regular boot as the = machines were not local and had no access to the console. There are = enough library changes that most services just will not start properly = and tend to hang.
