We were able to carve out enough time during 2018 to also assist Honda with their Hyperion upgrades to 22.214.171.124 and OBIEE + ODI to 12c.
All very successul, despit hitting issues due to the change in technology underpinning HFM. Its all now Java API and ODI 12c is not set up with a knowledge module for it.
We instead developed some basic stand alone Java routines that would set the required EPM class-paths, and allow data load/extract/calc/consolidate from ODI via basic shell-out.
There has also been some fun with Essbase patches, as Oracle now have a grace period for fix support, but nobody told their Planning developers so they still only certify an out of support Essbase. Madness.
