## Issue Summary We’re unable to upgrade our ICRC-1 ledger canister to any version released after **2024-09-13** due to stable memory compatibility issues. ## Technical Details **Current Working Version** : 2024-09-13 (commit: `5ba1412f`) **Canister ID** : `irorr-5aaaa-aaaak-qddsq-cai` **Network** : IC Mainnet ## Failed Upgrade Attempts Attempted to upgrade to the following ledger-suite-icrc releases, all failing with the same error: - ❌ **2024-10-17** - ❌ **2024-11-28** - ❌ **2025-01-07** - ❌ **2025-01-21** - ❌ **2025-02-27** - ❌ **2025-04-14** - ❌ **2025-05-22** ## Error Message ```auto Error from Canister irorr-5aaaa-aaaak-qddsq-cai: Canister called `ic0.trap` with message: 'Panicked at 'Cannot upgrade from scratch stable memory, please upgrade to memory manager first.', rs/ledger_suite/icrc1/ledger/src/main.rs:192:9' ``` ## Upgrade Command Used ```bash dfx deploy dusd_ledger --argument '(variant { Upgrade = opt record { token_symbol = opt "DUSD"; token_name = opt "Doxa USD"; } })' --ic --identity doxa ``` ## Root Cause Analysis The error suggests that ICRC-1 ledgers deployed before **2024-10-17** use **“scratch stable memory”** format, while newer versions expect **“memory manager”** format. This appears to be a **breaking change** in the stable memory layout. ## Questions for the Community 1. **Is there an intermediate upgrade path** between 2024-09-13 and 2024-10-17 that handles the memory format migration? 2. **Are there any migration tools** or specific upgrade procedures for ledgers stuck on pre-2024-10-17 versions? 3. **What’s the recommended approach** for production ICRC-1 ledgers that need to stay on older versions for compatibility? 4. **Will this be addressed** in future releases with backward compatibility support? ## Related Discussion Similar issue discussed here: [Upgrading old ICRC1 token to the ICRC ledger suite](https://forum.dfinity.org/t/upgrading-old-icrc1-token-to-the-icrc-ledger-suite/39663) Any guidance on safe upgrade paths or migration strategies would be greatly appreciated! ---

Hi @Vishnu, thanks for the details, and sorry to hear you’re having issues upgrading your ledger canister! Looking at the canister info and metadata, I’m a bit confused: ```auto $ dfx canister info --network ic irorr-5aaaa-aaaak-qddsq-cai Controllers: 2bfxp-uzezm-gf5ny-ztks2-ybgzc-4dfjc-7gdhs-he2ek-vdjfk-w4yph-fqe 6cfa5-kyaaa-aaaag-qdk4a-cai Module hash: 0xa170bfdce5d66e751a3cc03747cb0f06b450af500e75e15976ec08a3f5691f4c ``` The module has suggests that this canister is running [ledger-suite-icrc-2024-09-13](https://github.com/dfinity/ic/releases/tag/ledger-suite-icrc-2024-09-13). ```auto $ dfx canister --ic metadata irorr-5aaaa-aaaak-qddsq-cai git_commit_id e54d3fa34ded227c885d04e64505fa4b5d564743 ``` However, the `git_commit_id` metadata suggests it is running [a commit from October 17, 2024](https://github.com/dfinity/ic/commit/e54d3fa34ded227c885d04e64505fa4b5d564743). Thanks for pointing to the migration post @marc0olo! @Vishnu if you are able to upgrade after referring to the instructions in the post, feel free to disregard my follow-up questions. Just to clarify, you are running the Rust ICRC ledger from the [ic](https://github.com/dfinity/ic/) repository? Did you build the canister yourself, or download the WASM from a CDN? The error suggests that you are running a pre-2024-09-13 release of the ledger. Regarding your questions for the community: 1. _ **Is there an intermediate upgrade path** between 2024-09-13 and 2024-10-17 that handles the memory format migration?_ 2. _ **Are there any migration tools** or specific upgrade procedures for ledgers stuck on pre-2024-10-17 versions?_ 3. _ **What’s the recommended approach** for production ICRC-1 ledgers that need to stay on older versions for compatibility?_ 4. _ **Will this be addressed** in future releases with backward compatibility support?_ ---

@Vishnu The error message you posted: ```auto Error from Canister irorr-5aaaa-aaaak-qddsq-cai: Canister called `ic0.trap` with message: 'Panicked at 'Cannot upgrade from scratch stable memory, please upgrade to memory manager first.', rs/ledger_suite/icrc1/ledger/src/main.rs:192:9' ``` seems to be from [the 2024-11-28 release](https://github.com/dfinity/ic/blob/2190613d3b5bcd9b74c382b22d151580b8ac271a/rs/ledger_suite/icrc1/ledger/src/main.rs#L192). The earlier releases do not fail with that error, so if you could let us know what the error is when trying to upgrade to [the 2024-10-17 release](https://github.com/dfinity/ic/releases/tag/ledger-suite-icrc-2024-10-17), that would be helpful! ---

we are successfully upgraded our ledger canisters after reading migration guide ---

Thanks for reporting back, that’s great to hear!
