# Schema changes overview

> Beacon Chain deprecation timeline, replacement tables, and publication status

As part of ongoing schema updates and standardization, legacy `beacon.validator.*` tables are being replaced by `beacon.raw.*` tables. Use this overview for timelines and status; open each migration page for full column mappings and breaking changes.

<Warning>
  **Schema changes**

  The following tables will be replaced by **May 23, 2026**:

  * `beacon.validator.balances_latest` → `beacon.raw.balances_latest`
  * `beacon.validator.balances` → `beacon.raw.balances_daily`
  * `beacon.validator.index` → use `beacon.raw.balances_latest` (no separate registry table)
</Warning>

## Per-table migration guides

* **[`beacon.validator.balances_latest` → `beacon.raw.balances_latest`](/historical-data/supported-blockchains/evm/beacon-chain/schema-changes/balances-latest)** — Latest snapshot per validator; Wei → ETH floats, new withdrawal columns, `UNIQUE_ID`.
* **[`beacon.validator.balances` → `beacon.raw.balances_daily`](/historical-data/supported-blockchains/evm/beacon-chain/schema-changes/balances)** — Daily history; column reorder, `IS_SLASHED` → `SLASHED`, `UNIQUE_ID` format change.
* **[`beacon.validator.index`](/historical-data/supported-blockchains/evm/beacon-chain/schema-changes/validator-index)** — Registry retired; read equivalent fields from `beacon.raw.balances_latest`.

## FAQ

**Will queries break immediately?**\
No. Deprecated tables remain available until **May 23, 2026**.

**How do I convert Wei to ETH/Gwei?**

```sql theme={null}
raw_balance::numeric / 1e9
```

**Why use strings for balances?**\
To prevent floating-point precision loss. Wei values can exceed safe float precision.
