NOTE:  Use this chapter if you are upgrading from Siebel CRM version 15.0 to Siebel CRM version 15.5 or later, upgrading from Siebel CRM version 8.1.1 and later (SIA repository only) to Siebel CRM version 15.5 or later, or upgrading from Siebel CRM version 8.2.2 and later to Siebel CRM version 15.5 or later. For more information about incremental repository merge as it applies to different installation options, see the Siebel Installation Guide for the operating system you are using.

NOTE:  For Siebel CRM version 15.5 or later, running incremental repository merge is optional if you previously ran it for Siebel CRM version 15.0 or performed a new installation of version 15.0. However, even in these cases you must run incremental repository merge to be able to use certain new features of version 15.5 or later. For more information about these new features, see Siebel Patchset Installation Guide for Siebel CRM, 1614310.1 (Article ID) on My Oracle Support. (If you have already run incremental repository merge for Patchset 5 or later, then you do not need to run it again for subsequent patchset releases.)
