## Proposal for SNS-W to fix SNS-1 upgrade path
### Proposer: DFINITY Foundation
### Target SNS Governance Canister: zqfso-syaaa-aaaaq-aaafq-cai
---
This proposal will change the upgrade path to use different WASMs, but WASMs that are already available on SNS-W.

This will only affect the SNS that has the following governance Canister ID: zqfso-syaaa-aaaaq-aaafq-cai.

## Rationale

The upgrade path for SNS-1 was broken due to a version mismatch, resulting in SNS governance being unable to verify the success of any further upgrades.

This change makes governance the next response to the next request for an upgrade so that the logic to determine upgrade success is updated, allowing governance to unblock future upgrades.  
The first entry is the version SNS-1 currently self-reports, followed by an entry that upgrades governance, followed by an entry that upgrades ledger.
The final entry in the upgrade path is the same as an entry in the main upgrade path, resulting in putting SNS-1 back on the normal upgrade path.

## Useful background

To see what the upgrade path currently is, run
```
dfx canister --network ic call --candid ic/rs/nns/sns-wasm/canister/sns-wasm.did \
    qaa6y-5yaaa-aaaaa-aaafa-cai list_upgrade_steps \
    '(record {limit = 0: nat32; sns_governance_canister_id = opt principal "zqfso-syaaa-aaaaq-aaafq-cai";})'
```

To see the current version the SNS reports to be running:
```
dfx canister --network ic \
        call --candid ic/rs/sns/governance/canister/governance.did \
        "zqfso-syaaa-aaaaq-aaafq-cai" get_running_sns_version "(record{})"
```
