Documentum 7.1 to 7.2 upgrade

Hi All

Currently we have Content server 7.1 serving around 10+ docbases (High Availability) like CS1 (Primary CS) and CS2 (Secondary CS) .

Now I can't be able to build parallel environment and perform upgrade due to cost.

Can someone suggest better approach since we will not be able to upgrade all docbase in single day .

Can we upgrade content server 7.2 and few docbase to 7.2 on single day ,but keep other docbases as 7.1 version.

Any approach will be good help .

I believe in the upgrade manual, it does mention that you dont have to upgrade the docbase when you install newer version of the CS (binary files). So this would allow you to upgrade each repository individually.

It depends if you are on Windows or Linux/Unix. With the latter, you can install several versions in parallel. On Windows, you can only have one version.

I think OP question is whether docbases under one CS installation can run different versions?

It depends how you define "CS Installation". My understanding is that he has a machine with a CS 7.1 Installation and wants to install CS 7.2 on the same machine in order to run some docbases with 7.1 and others with 7.2. But perhaps I'm mistaken.

My understanding was:

He has one CS installation, and under that, he has multiple docbases. So, while upgrading the CS binaries happens once, but each docbase within that installation has to be upgraded individually.

So OP question would be is it possible if the CS binaries are upgraded to 7.2, and 1 docbase is upgraded to 7.2, can the reamining run in lower version?

In the 7.2 upgrade and migration guide:

"...It is recommended that you upgrade all repositories in Content Server to the same version."

This does not say its required. Since 7.1 and 7.2 are very similar, then I dont anticipate issues keeping some of the repositories at 7.1, after the CS has been upgraded to 7.2.

Yes I would have CS currently as Windows OS and I would like to do inplace upgrade only .

My concern there is some security level changes happen in CS 7.2 Specially AEK level ,So will that create any issue for docbases existing as 7.1

We will upgrade all docbases slowly to 7.2 but first I would like to upgrade 4 docbases over one time and later remaining .

My CS Operating System in Windows.

I am tring to do inplace upgrade of existing environment i.e 7.1

Planning to upgrade few docbase at one time and remaining in another weekend.

So concern is around can we keep all docbases up and running if CS is upgraded to 7.2

Yes you can do that upgrade the binary first then go selective on the repository. It's just a little more test effort in your test environment. We used this approach to go from 6.7 to 7.0 and it worked. Yours being 7.1 to 7.2 should be easy I guess.

- If you are so concerned about this, just submit a support ticket to EMC and get their confirmation.
