Multi-MMP or MMP migration checklist for live F2P titles
Analysis
By UA Ledger staff — 1 min read
Migrations during live seasons destroy cohort continuity. Checklist anchored to AppsFlyer attribution and SKAN schema docs.
Live F2P migrations that swap MMPs mid-season break cohort continuity even when both SDKs “look green”.
Checklist
- No blind cutover in a season peak — Attribution models differ by vendor (attribution model); dual-run first.
- Archive SKAN maps — CV decode notes historic schema is not available via API.
- Align windows — Re-attribution / re-engagement settings apply going forward (re-attribution window); write both MMP values.
- Explain deltas — Do not expect install and revenue parity without a bridge table.
- Freeze straddling cohorts — Payback cohorts that include both MMP eras need a labelled break.
- Partner postbacks — Remap events before pausing the old MMP.
Facts vs limits
| Fact | Limit |
|---|---|
| Models differ; historic CV schema limited; windows apply forward | Adjust/Singular migration runbooks not body-read here |
| Checklist is procedural | Not a named studio postmortem |
