Any ideas ? This was a build from S11.0 1111 and has had SRUs applied
root@ytc-s11-repo:~# pkg update be-name s11.1ga accept
Creating Plan /
pkg update: No solution was found to satisfy constraints
Plan Creation: Package solver has not found a solution to update to latest available versions.
This may indicate an overly constrained set of packages are installed.
The following indicates why the system cannot update to the latest version:
No suitable version of required package pkg://email@example.com,5.11-0.175.1.0.0.24.0:20120904T170613Z found:

I remembers Gerry shooting about this on at UKOUG Solaris talk .... checking his blog ... https://blogs.oracle.com/Solaris11Life/entry/solaris_11_process_enhancement_no I thinks it mentions an issue with the update you are attempting.
In essence, if I remembers correctly, one cannot upgrade from 11.(X).(SRU-LAST) to 11.(X+1)[base] ... one has to use the first SRU of the new release or later.
