Yes, you can upgrade one system at a time.  Mixed-release operation is
supported as a transitional measure during an upgrade.  It's mentioned
in the Installation & Configuration Guide.

You might use 'utadm -f' (and 'utadm -n' afterwards) on each machine
some time before you upgrade it, in order to minimise the number of
sessions that will be affected by the actual upgrade.
