🔄 Migration and Change Tracking

Moving changes between environments — and knowing who changed what, and when — is the difference between releases that ship cleanly and releases that go wrong. Arc+ provides automatic change tracking, side-by-side comparison, dependency-aware migration packages, and a Blame Report so root-cause investigation stays fast even months after a release.

What you'll find in this section

Compare

Side-by-side comparison of TM1 objects between two environments — see exactly what differs in rules, processes, dimensions, and structures before promoting anything.

Why it matters: eliminates surprises during migration. Reviewers can sign off on a concrete diff instead of trusting a developer's description of what changed.

Change Tracking

Every change to a TM1 object is recorded automatically — who made it, what changed, and when.

Why it matters: a complete audit trail is always available without anyone having to maintain it. Compliance teams get the evidence they need; developers get instant rollback to any previous version.

Migration

Build migration packages that automatically include all dependent objects, preview exactly what will change in the target environment, and execute the move with a recorded log.

Why it matters: migrations stop being a manual checklist. Releases are repeatable, dependencies are never missed, and the same package can be promoted through Dev → Test → Production with confidence.

Blame Report

For any line in a rule or TI process, see who last changed it and when — much like git blame for TM1.

Why it matters: when an investigation lands on a specific line of code, the next question is always "when did this change?". The Blame Report answers it immediately, without searching through change history.

Summary

Together these features transform TM1 release management. Changes are tracked automatically, differences between environments are visible up front, migrations include everything they need, and the historical record is always one click away. Teams ship faster, with fewer mistakes, and can explain every change they made.
