Description

Currently the only way to switch the extension version to which a stack version is linked is to perform the following actions:

• Stop the extension services
• Reregister (delete) the extension services
• Unlink the old extension version
• Link the new extension version
• Add the extension services back

The REST API should allow us to do an update action on the extension link. In this manner, if we were running an upgrade from HDP 2.6.1 to 2.6.3 (or something similar) which both use the HDP 2.6 stack version then we could perform the extension link switch as a manual step during the upgrade process.
