At my company we were trying to configure up documentum integrated with SharePoint 2007

but our main problem was that SharePoint was installed on Windows Server 2008 ( Hyper V) and documentum is only integrated to work on Windows 2003 so that was one of the big issues forced us to reconsider the solution.

but any ways here comes the things required to get the job done and from where to get them.

good resources describing the installation process for the Documentum server I found that link here

It is describing everything still we need to install  SMTP Server .

Also we need “EMC Documentum Archive Services for SharePoint” here

And “EMC Documentum Content Services for SharePoint” here

I hope the installation packages have contains step by step guide for installing them

i know it is very complicated process but still it worth it … but please make sure before proceeding with the steps you have windows server 2003

We had an environment with all DCTM & MOSS integration functionality, unfortunately that environment was based on DCTM 5.3 version. We are at the moment working on a new setup using DCTM 6.5 SP1 & MOSS 2007. The thing is that actual products (Content Services & Repository Services for MOSS) are NOT available yet. Anyway, we got our hands on Content Services for MOSS and that is up and running
