I don't have anything particular to add. I think

update app template according to new SDK and test with ignite

Can be separated for all scaffolding commands to work on them in parallel, this could be the complex part of the PR

May we close #2156 @ilgooz ?

Hey, I created this PR which is using feat/sdk-ibc-upgrade as the base branch.

I propose to target feat/sdk-ibc-upgrade as the base branch for the future PRs as well and once all of them are merged, we can extensively test that branch before merging it to develop.

This approach could also give us flexibility if we want to make another release from develop while working on this feature in feat/sdk-ibc-upgrade.

[fadeev]

I can work on the documentation for this.

[ilgooz]

@fadeev That would be great! 🙏

[aljo242]

Remaining work on #2677 is to modify the templates and proto-gen

Since @tbruyelle is vacationing, @jeronimoalbi would you mind taking the part related to running the tutorials and migrating them if there is a need for it?
