Currently we are using Teradata TTU 14 and Informatica 9.1 and 9.5.1. As per my understanding Teradata has declared end of support for Teradata 14 in 2016, so we need to know
1. if Teradata TTU 15 will be compatible with 9.1 and 9.5.1 versions of Informatica.
2. If not then do I need to upgrade Informatica to 9.6 .
3. Is there a way I can delay Informatica upgrade but with some changes can continue using Informatica 9.1 & 9.5.1. What are those changes.
4. When is the most likely end of life for Teradata 14.
In TAYS the compatability documents will give you the answer.
In short: 9.6.1 is certified with TTU 14.10. Not higher. However TTU 14.10 is 2 versions upward compatible, so TD 15.10 is okay, TD 16.00 is not okay.
