> Affects Versions: 2.1.0.

>
> When the upgrade is cross-stack (HDP-2.2 -> HDP-2.3), the wrong upgrade pack
> is used to create tasks.
> When the user is presented an option to Downgrade, the following request is
> sent to the server:
> {noformat}
> POST /api/v1/clusters/c1/upgrades
> {
> "RequestInfo": {
> "downgrade": "true"
> },
> "Upgrade": {
> "repository_version":"2.2.6.0-2772"
> }
> }
> {noformat}
> This request makes the backend choose the HDP-2.2/upgrade-2.2 upgrade pack.
> This is ok if the source and target versions were both 2.2, but when going
> from 2.2 to 2.3, we should be picking the upgrade-2.3 Upgrade Pack. The
> request in this case should be:
> {noformat}
> POST /api/v1/clusters/c1/upgrades
> {
> "RequestInfo": {
> "downgrade": "true"
> },
> "Upgrade": {
> "from_version": "2.3.0.0-2220",
> "repository_version":"2.2.6.0-2772"
> }
> }
> {noformat}
> The code to handle from_version is already implemented so no changes needed
> on the BE.
