Upgrading from V7.4 (and earlier)
Use IBM® Installation Manager to install Tivoli Netcool/OMNIbus V8.1. During installation, you can use Installation Manager to automatically migrate your existing data. Alternatively, you can manually migrate your existing data after installing V8.1.
On UNIX and Linux operating systems, you can continue to run your existing Tivoli Netcool/OMNIbus installation in parallel with the newly upgraded installation. You must, however, ensure that the set of ports in the two installations is different. You can change the ports in the newly upgraded installation by editing the default values in the $NCHOME/etc/omni.dat data connections file. After you change the ports, run the nco_igen utility to generate the interfaces file that stores server communication information.
