About future of the Content Deployment feature for SharePoint 2019

This article is about future of the “Content Deployment” functionality in SharePoint.
SharePoint production team is not improving the feature till SharePoint 2013 and they will not invest “Content Deployment” in newer SharePoint Builds.
So you should be consider to find an alternative on it.

Feature itself It is not depreciated but it will be present in SharePoint “AS IS” for backward compatibility mode and if any new feature implemented in SharePoint 2019 if it is not convenient or breaks content deployment, it will not going to be adjust/fixed.
Another meaning; SharePoint engineering team will not consider the effect for any new features on Content Deployment.
If you want to continue to use “Content Deployment” Either you should disable the newly implemented features in SharePoint 2019 (Where it may not possible some scenarios) or you need to switch an alternative (Mostly 3rd party products or manual operations)

Our official statement on this issue: Content deployment was announced as NOT recommended since SharePoint 2013 and also this statement valid for higher builds, with limitations and alternatives called out here https://blogs.technet.microsoft.com/tothesharepoint/2013/07/15/changes-to-content-deployment-in-sharepoint-server-2013
While it has not been formally deprecated, it has a limited degree of support, including not supporting the deployment of many features.
