My current task at hand is to convert an version 3 universe to 4.1 along with numerous.
Eventhough there is the upgrade wizard in the supervisor module. However, the manual didn’t explain enough details about the process. I have general questions like: Does it delete the old universe from the BO 3.1 repository after the universe converted into 4.1 repository?
My bottom question is: Did anyone bother to write down a more detail procedure, a white paper about the issues & problems, or the DOs & DON’Ts list? If so, please let me know where to find them.

My advice or comment is greatly appreciated.
Monica,
I did not write anything down (although I’m sure someone did), but I did convert a rather large, multi-universe system from 3.1 to 4.0. It was not pretty.
Your BO 3.1 repository will remain untouched by the process, because the 4.0 repository will be created under a whole new owner. Note: the process does not include any way to automatically convert documents in the repository to 4.0. You will have to open each one individually.
Depending on how complex your universe is, I would recommend that you just rebuild the universe in 4.1 rather than trying to convert it. Unless the conversion routine has been improved since I used it in 4.0.5.6 (possible), I found it to be difficult to use. In fact, the application crashed every time I tried to run it. I have heard others comment similarly.
By re-building the universe, you will not only guarantee a clean conversion, but you will give yourself some good experience with Designer, as well.
I converted about 20 universes from 3.1 to 4.1. The wizard did a very good job of converting them. I don’t have anything formal written up about converting universes, but here are some of the guidelines that I used:
All numeric objects are converted to measure objects. Some objects (such as ssn or phone number) should be dimensions, and they will need to be changed to dimensions.
You may need to edit the connection in the 4.1 copy of the universe. Most of ours did not convert properly. This is a very quick fix.
If you used Oracle, and your 3.1 universe used the public synonyms, we were unable to get a workaround to read public synonyms in 4.1. Our DBA created some private synonyms, and we just added a qualifier to the table in Designer.
After this, I just checked our objects definitions, our joins, and our contexts. All of these converted properly, and I did not need to change any of them.
