Hi @Ofelia Arias.
A quick clarification first, because this trips a lot of teams up:
- TBM = the framework and taxonomy published by TBM Council
- ATUM (Apptio TBM Unified Model) = Apptio's productized implementation of TBM
In our upcoming 12.11.17 release (targeted for Sep 26), customers will have access to the new reference list files for TBM v5.
Also, you can find the data on TBM Council's Taxonomy web page here.
Documentation for our IBM Apptio customers interested in migrating will become available sometime in 2Q2026 or earlier to coincide with native support for TBM v5.

Subject: How to migrate from ATUM v3.0 to v4.0
We would like to migrate from ATUM v3.0 to v.4.0 but I haven't found any documentation about it. I don't even know where or how to get the Cost Pools and IT Resource Towers reference list files.
Any recommendations?
