Tm1 9.1 or 9.3 compatiable with TM1 9.4

[sethihe1]

Hi

In my company, various deapartment using TM1 different version such as 9.1 SP2, SP3 and 9.3.

Now, for my department , we are planning to install TM1 9.4.
But, problem is that our Users accessing TM1 instances/cubes from different server.

They are using TM1 9.3 Client and able to access TM1 9.1 SP2's cubes and TM1 9.3 in the same Client (9.3)

Here my question is that If I install TM1 9.4 Server, so , these ppl can access 9.4 cubes/instances in TM1 9.3 client.

Because, other department not very keen to install 9.4 and we have to install very quickly.

Thanks & Regards

No they are not, especially 9.4. For the sake of your IT departments sanity i would seriously suggest convincing your key stakeholders to agree on one version. Supporting multiple versions is a nightmare and some functionality changes between versions makes working on them difficult too.

Also....
I don't believe there is a 9.3 version of TM1. Could you select help\about from Perspectives and post the image?
Why do you _have_ to go 9.4? What do you need that only that version can do?

9.4 data structure is also in Unicode, so I doubt it can read 9.3 or vise versa.

Isn't the question about compatibility of clients with servers? I don't know but I would have thought that a 9.4 client could connect to a 9.1 server. To my mind, not being able to do so would be quite a problem when testing - working on a live 9.1 version while testing a dev 9.4 version. I'd expect Iboglix would be on top of that especially as I don't think the client code is unicode, just the server.

However I quite agree that moving data on _servers_ between versions is a different story.

it is, but they change the clients just as much as the servers and i wouldn't trust anything to work 100% accurately unless i had the same client as server versions. IIRC in 9.0 we have a "disconnect self" option, but in 9.1 i think they changed it to "log out" or something similar. It probably does work fine, but then why risk it?

Thus spoke the Operations guide (under the ClientVersionMaximum parameter entry of the tm1s.cfg section, page 2-16):

You cannot set ClientVersionMaximum to a value greater than the currently installed server version. You cannot connect newer client versions to older server versions.

(Whether it ever works (after a fashion) is of course a whole 'nother thing...)
