Migrating from v9 to v10

This guide provides instructions for migrating to a new version of ibc-go.

There are four sections based on the four potential user groups of this document:

• Chains
• IBC Apps

    - [ICS27 - Interchain Accounts](#ics27---interchain-accounts)

• IBC Light Clients

Note: ibc-go supports golang semantic versioning and therefore all imports must be updated on major version releases.
