You can move the Physical solaris 10 installation in the M4000 into a Virtual Oracle VM for SPARC I/O root-domain, running Solaris 10 , in a Fujitsu M10 server or an Oracle T5 server
without having to reconfigure you application environment.
Even though its theoretically possible to move an application from Solaris 10 to Solaris 11 without reinstalling the thing, providing the Application vendor supports it, You probably do not want to !
You dont want to because:
The application should most probably be relinked with new libraries in Solaris 11 / Studio 12
ZFS file system layout vs UFS filesystems
New networking scheme ( including vNIC's ) in Solaris 11 might require application reconfiguration.
If this is Oracle DB 12c you are moving....
I would install ORA DB 12c fresh on new server with Solaris11 and then either take a short service break to move the database filesystems to the new server or if
a service interuption is not possible ( ie a 24/7 system ) use the Golden Gate product to replicate the database to the new server.
