Upgrading to Version 8 from 7.1

[travis]

Hi - I'm looking to find some opinions on my upgrade strategy. I will be upgrading our DS environment in the next month, and will be starting the process on a clean server. What would be the best approach for getting the 7.1 version on the server? Can I simply take a backup of the existing environment and drop it on the clean server or do I have to go through the full install of 7.1? Also, are people finding it easier to have both the 7x version installed along with 8 on the server for compatibility testing?

According to the IBM upgrade documentation, you must upgrade 7.1 to 7.5 first before you upgrade to 8.0.1.

Here's the verbiage from the IBM site...

Earlier DataStage versions - UNIX and Linux servers

If your version of DataStage is earlier than version 7.0, then you cannot upgrade directly to IBM Information server. There are two available upgrade options and a co-existence option:
1) Upgrade your DataStage server to DataStage version 7.5.2 and then run the IBM Information Server installation program to upgrade to WebSphere DataStage.
2) You can save your DataStage design objects and associated data, then remove your old installation of DataStage before installing IBM Information Server. You then restore your objects and data. You can also use this option to move DataStage to a different computer.
You can maintain your existing version of DataStage server, and install IBM Information Server alongside it.

I do not interpret those statements to mean you have to go to 7.5.2. It's an option, but unless I'm missing something as long as we are on the 7x version we should be fine.

I imported a DataStage 3 export file into the Information Server. I think it was DataStage 3 export file, the "ToolVersion" was "3" and the extract date was 2002 and the "Exporting Tool" was "Ardent DataStage Export". Imported routines, batch jobs and server jobs without a problem. I think there is a difference between upgrade and import. You can only upgrade from 7.* but you can import from earlier versions.

(This post was updated Sep 28 to change 7.5.2 to 7.*)

I'm in meetings with IBM today and I asked this very question, and just as the documentation states you only need to be on version 7x to upgrade to version 8.

Please stop spreading bad information.

This reqest is for all,

2) You can save your DataStage design objects and associated data, then remove your old installation of DataStage before installing IBM Information Server. You then restore your objects and data. You can also use this option to move DataStage to a different computer.

Saving the Datastage design objects and associated data , how it can be done. Is it through exporting the .dsx files of the datastage jobs ?

Please let me know. We are going for from version 5.0 to version 8.0

Yes, it is done through exporting to .dsx files.
