Upgrade from 8.2 to 8.4

[hiranb]

Hi,

      Do you have to redo customization in cognos connection after you upgrade from 8.2 to 8.4? If anyone has instructions of upgrading from 8.2 to 8.4, can you please share it ?
Thanks

Hi
I would think you would need to redo the customisations. What sort of customisations are you talking about? Have you modified the xml files in the installation or something like that.

Cheers

Whenever you upgrade of even apply a fixpack to cognos, it automatically resets all configurations. This will include system.xml, any files in the bin folder, any files in the configuration folder and so on.

This is because the file layout may change. If you've elected you keep a backup during the upgrade process, you should be able to find all these files in the uninstall folder so that you can reapply your customizations. I highly recommend you don't just stick your old config files in the new cognos install folder, as 8.4 is vastly different from 8.2.

Compare, and reapply them one by one.
