Managing API Instance Versions
After you publish new version details for an API definition to Exchange, you must update the Asset version of your deployed API instances in API Manager to reflect the changes.
For more information about versions in Exchange, see Asset Versions.
To change the asset version of an API instance:
Navigate to Anypoint Platform > API Manager.
In API Administration, click the name of the API instance for which you want to change the version.
Select Actions > Change API specification.
In Asset version, select your desired version.
