10.2.2 Backward Compatibility

[cipher]

hi All,
This is regarding the TM1 backward comparability issue. Recently we upgraded to 10.2.2 with Fixpack 6. Architect of 10.2.2 FP6 server also has an adminhost of 10.1. The problem that I saw was, when I try to connect to TM1 instances which are running of 10.1 TM1 Server then it gives me an error of version incompatibility.
I was aware that client with 10.1 cannot connect to TM1 instance which are running on 9.5.1/2.

Is there any solution to this problem except upgrading other tm1 to 10.2.2?
Can we install 10.1 client on a server which is running 10.2.2 FP6?

Regards,
cipher

I am afraid you have no option other than upgrading to 10.2.2.It works vice versa but not this way around.Thanks

Hi Cipher,

Generally speaking (with a few exceptions) you can always use an older client to connect to a newer server but not the other way round.

So if you have to work with multiple versions as a developer you can normally get around it by remoting to each server and using the relevant client there... or having multiple clients via citrix depending on your set up.

You can have multiple clients installed on 1 machine but its gets very messy so I wouldn't recommend that.

In the event that a user or developer needs to connect to different versions regularly from their own desktop I would normally just use the oldest server version's client - as it should work with all of them.

Thanks Declanr for your reply.

With above quotes, Can I install 10.1 client in my TM1 server where TM1 10.2.2 FP6 is installed? (by making sure that, installation folders are different for both TM1 setup).
The reason, I need to connect to older TM1 Instance with the newer one is because, we have many automated reports which reads data from 2 TM1 Instances which are on (10.2.2 and 10.1). If I dont install 10.1 client on 10.2.2 server then, I am afraid that reports will not be able to run on its own; and I will have to run them on my local machine manually which has 10.1 TM1 installed.

You can install it there as well; the easiest method would be to just copy the bin folder from another install.

What sort of report is accessing both though? Is it just perspectives or do we mean BI?
Could it not be run from a clients machine rather than the server?

[cipher]

Thanks for a quick reply Declanr,
Those are perspective reports. We can certainly run from client machine, but we dont want to put it on them yet, may be later.

I will certainly give a try to copy the bin folder of 10.1 and try to use its tm1p.xla file and see how it can connect to both the instances. I will let you know my findings.

It might be worth noting that the SSL version was changed in FP6 and by default older clients (using the older SSL version) are blocked from connecting. You can enable support for older clients with the SupportPreTLSv12Clients tm1s.cfg parameter.

Just to let you know that, I already enabled SupportPreTLSv12Clients setting in Cognos TM1 Configuration Window. If this parameter is not set to TRUE then Clients running FP6 will not be able to see other TM1 instances running on earlier version. By ticking this TRUE, at least earlier version of TM1 Instances pop-up in Architect, and when try to login, it says TM1 Version in compatible.

What about the ClientVersionMinimum abd ClientVersionMaximum parameters? What are your settings for these?
