Hi All,
We are using CA 11.1.7, but noticed some of the developers are having earlier FM version.
Do we really need to upgrade FM every time we upgrade the server? Do you see any problem if we use earlier version of FM.
Appreciate your feedback.

FM packages are forward compatible. That means that a FM package created in a version of FM will continue to be usable in Cognos Analytics for subsequent releases without manual intervention.
Similarly, a package created with a FM of version x will publish and run in CA x+1 ... n.
Since FM is in maintenance, the schema is probably not going to have many revisions so you probably will not need to be particularly swift in updating your FM.
When a FM model is opened, FM will look at its schema value and perform upgrading of it before loading the upgraded version of the model into memory. This means that if you save that model older versions of FM will not be able to use the model.
Thank you for your reply and I understand about the forward compatibility.
My question is more towards to the FM client version. The model/package could be existing or new.
Case 1)
I have Cognos 11.1.7 server, but if I continue to use 11.1.5 version of FM and update the model and publish the package to the 11.1.7 server
Csse 2)
I have Cognos 11.2.0 server, but if I continue to use 11.1.7 version of FM and update the model and publish the package to the 11.2.0 server
Do you see any issue with these above cases. What is the recommended approach?
When we would need to enforce the developers to upgrade the FM version installed on local machine.
Thank You,
AJ
In both cases every thing should be OK. I thought I covered that below but I guess I bought pith at the expense of clarity.
QuoteSimilarly, a package created with a FM of version x will publish and run in CA x+1 ... n.
If you have 11.1.5 FM and you publish a model from it to a 11.1.7 server then a 11.1.5 schema FM model package is published. The fact that the server is a higher version should not matter. The same for your case # 2. For that matter 11.1.5 FM should configure to a 11.2 server and you will be able to publish to it.
Thank You!! very much for the clarification.
