Cognos BI upgrade from 8.2 to 8.4

[kvuppala]

Hi all,

Our organization wants to upgrade Cognos BI from 8.2 to 8.4 directly. I am wondering if any of you have done that already and would like to know more about pros and cons of doing it. Appreciate if any one shares their experience in how the upgrade went whether it was smooth or has to make so many changes in the reports, packages etc after the upgrade.

Thanks in advance!

hello,

it depends on how large your infrastructure is and how much customisation you have already made for your 8.2. there is no single well-defined methodology for migration but every such activity needs to be worked out.
it would be easiest if you have your 8.2 BI with all defaults and it its a single server installation.
there will be definitely some overhead from the developers point of view as they would need to validate all their reports to make sure that they work fine in 8.4 BI. They would also need to upgrade their FM models and fix any upgradation issues.

Hope this helps a little bit.
