Thanks for your reply. I am going to install it in two separate boxes. Do I have to redesign the cognos portal or how to get 8.2 cognos portal settings to 8.4?

Browse All TopicsHi,
I have few questions regarding upgrading from 8.2 to 8.4.
1) Is it a good practice to have both development and production on one server? If so what would be the best scenario.
2) If any one has upgraded from 8.2 to 8.4 could you please provide instructions on installation?
3) What issues would you come across while upgrading to 8.4?
Thanks.

When you split the servers you will have to change the portal for the environment you move to the second server. I am not sure how your environment is set up but I was able to have my network group create an ?alias? so my users just type Cognos or Cognosdev(could be any name) in the browser and they are directed to the correct server. This lets me change boxes without disturbing the users as I can just have the network team point the ?alias? to whatever box I wnat them to go to.

It is not a good practice to have development and production on the same server. In fact this is a recipe for disaster. In fact the best practice would be to have two dev and two prod boxes. This allows you to upgrade in place and test side by side old version new version to find performance and program bugs.
The upgrade is not really an upgrade of the cognos software. You uninstall the old and then install the new software. The content store is what is truely upgraded. Here are the steps I remember but I am not in the office so I can't look at my notes. I may have overlooked something.
1) create a backup copy of your content store
2) export your configuration file
3) create a copy of your configuration file not in the cognos directory.
4) create a copy of any customization files in a non-Cognos directory.
5) Uninstall cognos8.2
6) Install cognos 8.4
7) After the install open the configuration file you saved when you validate
8) when you validate the configuration it will upgrade the content store (warning make sure you have a backed up copy if anything goes wrong here you will need it.)
9) If all goes well you are done... now go test all of your reports
The biggest issue I think you will run into is if you have used any Javascript. Some of the naming conventions have changed. So much of your Javascript will probably not work. If you are just using standard reporting you should find that your reports are going to actually run a little faster.
