Migration of datastage code to Talend

[Anonymous]

Hi,

My team is planning to move on to Talend from Datastage. We are in initial stage right now, were just trying to figure out if we can migrate Datastage code directly to Talend.

Can anyone help me with any thoughts.

Yeah why not ... your goal is migration ( I assume ) ? or integration , like part of your daily ops.

IBM should have it available via api's / java packages ... you can easily add libraries to Talend via preferences. If you want to build custom components follow the tutorial to speed things up. 

IBM Docs

But I would not recommend importing it (no experience in doing so) , it probably works to 'generate' your blueprint, but Talend is designed with its own "philosophy" and in a way you should stick with that.  I would only import/export (metadata)schemas...  to easy datamodelling part.

Seperate concerns and avoid getting all mixed up due to introducing different techniques, conversions and even versions. Before you know it your Talend proces relies on package X and the company upgraded to Y.

Hello,

Thanks for writing back.

I am trying to migrate my Datastage jobs to Java using Talend by importing the .dsx files and I completely agree with you that it is a mess to go by this process, but I have a huge number of jobs at hand and this is the fastest and most cost effective way for me. As Talend is able to give me something while importing a job I am not sure why it is not able to detect it.
For example, If conditions of Datastage are being converted to MITI.IFF but it is no where in the system routines hence it is not being detected. Is it related to this MIMB?

A DataStage function JulianDayFromDate is being converted to DataStage.JulianDayFromDate but is not getting resolved.

So the problem goes on for all the functions of Datastage so I just want to confirm if I am not missing out on importing any package/routine for the same.

I would also appreciate if there is anything that you/the community can suggest me for my problem.

Thanks
