 ### Migration to fix support for base denoms with slashes
 
 As part of [v1.5.0](https://github.com/cosmos/ibc-go/releases/tag/v1.5.0), [v2.3.0](https://github.com/cosmos/ibc-go/releases/tag/v2.3.0) and [v3.1.0](https://github.com/cosmos/ibc-go/releases/tag/v3.1.0) some [migration handler code sample was documented](https://github.com/cosmos/ibc-go/blob/main/docs/migrations/support-denoms-with-slashes.md#upgrade-proposal) that needs to run in order to correct the trace information of coins transferred using ICS20 whose base denom contains slashes.
