Migration Guide

Upgrading ETHOS.TSAM is split into two guides, one per major step. Pick the one that matches the version you are coming from.

You are on	Read	What it covers
v3	Migrating from v3 to v4	The pipeline rewrite: removed deprecation shims, and the behavioral changes (weight semantics, column order, resolution defaults) that can move your results.
v2	Migrating from v2 to v3, then v3 to v4	The move off the class-based TimeSeriesAggregation API: a mapping for every old parameter, result access, tuning, and plotting.

Coming from v2? You need both.

The class-based TimeSeriesAggregation API was deprecated in v3 and removed in v4. The v2 to v3 guide carries the full parameter mapping you need to move off it; the v3 to v4 guide then covers what changed underneath.
