+# Anchor 1.0.0-rc.5 Migration Reference
+
+## Proven pattern (from basics/counter/anchor)
+
+### Cargo.toml
+- Change `anchor-lang = "0.32.1"` → `anchor-lang = "1.0.0-rc.5"`
+- Change `anchor-lang = { version = "0.32.1", ... }` → `anchor-lang = { version = "1.0.0-rc.5", ... }`
+- Same for `anchor-spl` if present — change to `1.0.0-rc.5`
+- Add comment: `# Anchor 1.0.0-rc.5 — pin to RC until stable release`
+- **REMOVE `interface-instructions` feature** if present (removed in Anchor 1.0). This affects transfer-hook projects.
+- Keep all other features as-is (`idl-build`, `init-if-needed`, `cpi`, etc.)
+
+### Anchor.toml
+- Remove `[registry]` section if present (no longer used in Anchor 1.0)
+- Keep everything else
+
+### package.json
+- Replace `"@coral-xyz/anchor": "..."` with `"@anchor-lang/core": "1.0.0-rc.5"`
+- Bump `"typescript"` to `"^5.3.3"` if it's on 4.x (required for @solana/web3.js peer dep)
+- Keep everything else
+
+### TypeScript files (tests/*.ts, migrations/*.ts)
+- Replace `import ... from "@coral-xyz/anchor"` → `import ... from "@anchor-lang/core"`
+- Replace `import ... from '@coral-xyz/anchor'` → `import ... from '@anchor-lang/core'`
+- Replace `require("@coral-xyz/anchor")` → `require("@anchor-lang/core")` if any
+
+### Rust source code (lib.rs etc.)
+- Usually NO changes needed
+- If `AccountInfo` is used in an Accounts struct, replace with `UncheckedAccount`
+- If duplicate mutable accounts exist, add `#[account(dup)]` constraint
+
+### Build verification
+- Run `cargo build-sbf` in the anchor project directory to verify Rust builds
+- Run `pnpm install` to verify deps install
+- Do NOT run tests (no validator available)
+
+### interface-instructions removal (transfer-hook projects)
+For projects that had `features = ["interface-instructions"]`:
+- Remove that feature from Cargo.toml
+- The `#[interface]` attribute is removed — check if the program source uses it
+- If it does, this needs manual intervention to refactor
