DSXchange

Hi DataStage Gurus,

We are in the process of upgrading DS 8.5 to DS 9.1. Our current architecture is single services & Metadata tier and multiple engine tiers (one per region). All engine tiers are referrring to single services tier configured in a separate LPAR.

I would like to understand the below questions.

1. Two versions of services tier can be deployed into a single LPAR?
2. Higher version of Services tier (for eg. 9.1 services tier) supporting to multiple versions of engine tiers (for eg. Engine tier 8.5 in a LPAR and 9.1 in another LPAR)

Points to be considered / taken care while implementing any one of the above approaches for DS upgrade.

Appreciate it if you could share your expertise ideas / lessons learnt if you had done similar upgrade.

Thanks & Regards
Elavenil

The answer to question 2 is no. You would not even be able to register an older version of the DataStage engine to a later version of the Services tier. Also, 9.1 and 8.5 do not support the same versions of WAS.

The answer to question 1 is maybe. You could possibly do it with two completely separate installations of WAS.

Refer to the IS 9.1 Migration guide for additional information.

Regards,

Thanks James for your quick response on this.

Point noted.

I will explore the question no.1 to conclude whether it is possible to do that.

I will share the info once it is tested.

Thanks for sharing URL for 9.1 migration.
