If you are upgrading from the Solaris(TM) 2.5.1 to the Solaris 2.6 operating environment, and printer configuration information resides on the system being upgraded, you must convert the Solaris 2.5.1 LP configuration to the format that is used by the Solaris 2.6 LP print services. If you don't, the printers on the Solaris 2.6 system may not be configured correctly.
