Having now been through two upgrades to Cognos Planning v 8.4, here are a few suggestions:

1. Stay with 32-bit servers. Cognos Planning is a 32-bit application and you won’t gain much of a performance edge with a 64-bit machine. I had some issues with IIS in the 64-bit environment.
2. Use physical servers, and avoid VMware (virtual servers). Cognos does not recommend these.
3. Consider doing a proof of concept in a development environment before upgrading directly to production. I experienced a number of technical issues with both upgrades along the way. Doing a proof of concept is alot of extra work, but at least you’ll know what to expect when you move from development to production.
4. In Cognos Planning 8.4, you can still use Access Manager for authentication. However, I would recommend using Active Directory.
5. Use the migration wizard to copy your models over. All of the data in the Analyst cubes as well as Contributor cubes will come over, along with the eLists. You will have to recreate the admin links. If you’re going from 7.1 to 8.4, you’ll need to move the models over manually. I can tell you how to do this.

Feel free to contact me directly with any questions. I look forward to reading your comments.

I am at the IBM training center in Dallas as I write this. It is Day Five of the Cognos TM1 developer class. The IBM instructor for this class is Steve Harris, and he has done an excellent job.

I must say that I am very impressed with the capabilities of TM1. It is very different from Cognos Planning, to say the least. Here are just a few of the differences:

1)      As you might already know, TM1 is memory-resident on the server. This technology enables developers to build gigantic cubes. It is not unheard of to have cube sizes in the billions. A cube in TM1 can have up to 256 dimensions. Updating or recalculating a cube is very quick.

2)      It is customary to have all cubes in a TM1 model as part of a single application (or “Server Instance”). This is quite a departure from Contributor, where I have seen as many as ten to fifteen applications that make up one overall model.

3)      There is no such thing as a “Synchronization” or “Go To Production” in TM1. Once you make a change to a cube, to a dimension, or change the rights, the user view is updated immediately.

Another big advantage that TM1 has over Cognos Planning is the “drag and drop” capability within dimensions. You can create hierarchies using this method, which means no more dealing with eLists stored in Excel.

One other difference is that the scripting of the rules and calculations in TM1 are done outside the basic user interface, which can be challenging for non-technical business users.

In summary, there are many compelling reasons to choose TM1 over Cognos Planning. Cognos Planning isn’t going away anytime soon. Both are great tools for budgeting and forecasting.
