I wonder if it would be possible to "upgrade" from an OpenIndiana install (151a) to the current Solaris release (11.1) using the IPS.
What I have done so far:
- added the "solaris" publisher using
pkg set-publisher -g http://pkg.oracle.com/solaris/release/ solaris
- removed the "opensolaris.org" and "openindiana.org" publishers (just to make sure)
- tried to start the update process using
pkg update --acceptor explicitly setting the release name
pkg image-update --accept --be-name Solaris_11- both backed out stating there are "No updates available for this image".
