Can this be ignored in practice, or is it a real issue?
It's real! You cant send and receive between versions of ZFS. > > > (Speaking as a sysadmin, I certainly hope that it is a misplaced > warning.

If you use external storage array attached via FC,iscsi,SAS etc, you can just do a 'zpool export', disconnect the storage from the old server, attach it to the new server then run 'zpool import' - and then do a 'zpool upgrade'.
