996	v0.22.0	For chains that were scaffolded with Ignite CLI versions lower than v0.22.0, changes are required to use Ignite CLI v0.22.0.

Upgrading a blockchain to use Ignite CLI v0.22.0

Ignite CLI v0.22.2 changed the GitHub username from "ignite-hq" to "ignite", which means the imports must be fixed to reflect this change.

1. In your go.mod file find the require line for Ignite CLI that starts with github.com/ignite-hq/cli and is followed by a version. It looks something like github.com/ignite-hq/cli v0.22.0, and replace it by github.com/ignite/cli v0.22.2.

2. Make a bulk find and replace in the import statements for github.com/ignite-hq/cli to be replaced by github.com/ignite/cli.

3. Finally, run go mod tidy and ensure there's no mention if ignite-hq/cli in your go.sum file.

This update includes an upgrade to the ibc-go packages. Please make the according changes:

1. Upgrade your IBC version to v3.

   1. Search for github.com/cosmos/ibc-go/v2 in the import statements of your .go files and replace v2 in the end with v3

   2. Open your app.go,

      • Update your transfer keeper by adding another app.IBCKeeper.ChannelKeeper as an argument after app.IBCKeeper.ChannelKeeper

      • Define var transferIBCModule = transfer.NewIBCModule(app.TransferKeeper) in your New() func, and update your existent IBC router to use it: ibcRouter.AddRoute(ibctransfertypes.ModuleName, transferIBCModule)

   3. Open your go.mod and change the IBC line with github.com/cosmos/ibc-go/v3 v3.0.0
