# ISO20022 | Data That Pays | Final 45‑Day Burn‑Down week | 9

What actually changes on cutover
Why it matters: Day‑1 is about what really flows cross‑border on CBPR+, not domestic RTGS timelines.
* CBPR+ ≠ RTGS. Cross‑border messaging runs on FINplus; local RTGS migrations follow their own schedules.
* Day‑1 scope. Payment instructions move to pacs.008/009; use the current CBPR+ usage guidelines.
* What retires where. Legacy MT for cross‑border payment instructions is phased out on the CBPR+ lane; local MT usage may persist domestically until each RTGS goes ISO.
* Translation is lossy. Expect truncation of structured fields (address, purpose) when falling back.
* Do this week. Confirm FINplus RMA, endpoint reachability, and schema version aligned with counterparties.
