With the move to DXP Cloud, users can more readily iterate entire Liferay DXP stacks for development or production. This also means that the requirement of having two separate environments (1 staging + 1 production) for staging is no longer needed. With this in mind, Remote Live Staging is not supported within DXP Cloud.
“Local Live Staging” is the supported staging feature for use within DXP Cloud. If you need additional information about how best to migrate your staging strategy for use within DXP Cloud, please contact Liferay Support.
