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.
The API Asset version can only be upgraded or downgraded within the same major version (minor and patch versions). If you need to upgrade to a different major version, you must create a new API Instance.
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.
-
Click Change.
