Are you sure you want that ?
ODI 126.96.36.199 is out of grace period. Bugs on top of this version are no longer fixed.
ODI has no functionality for downgrade.
ODI can only be upgraded.
Thanks Adrian , Is it recommended to install standalone ODI 188.8.131.52.0 on BDA uninstalling the default version which comes along with BDA 4.12(ODI 184.108.40.206.0 ) ?
You can install any ODI version technically.
The problem is if it is supported.
Because to install ODI is very simple. Most challenging is to integrate ODI with Cloudera components: Hadoop, Hive, etc.
I suggest you to move this thread to Big Data Appliance, because you need an answer from BDA point of view.
From ODI is very simple: install the version you want - bug the integration with Hadoop is more complex.
