Arcpy API vs ArcGIS Python API - eventual deprecation of arcpy?

Question

This falls under a more long term strategy question (which is also related to the Python language long term strategy as well...).

Is it the plan to eventually deprecate the Python 2.x arcpy API in place of this?  In other words, if I was to refactor all my old arcpy scripts to this Python ArcGIS API supporting Python 3.x, would that be unnecessary work, or is this something that is going to come up eventually anyway?

Also, as someone that relies heavily on my arcpy scripts (including arcpy scripts for redeploying server instances, publishing services, ingesting data to RDBMS'), can someone speak to where it might be appropriate to start learning this API and where appropriate to continue using the older arcpy API...if at all?

Thanks

Christian Wells,

I am all new to the ArcGIS API for Python. However, is it possible to access online layers with the ArcGIS API for Python, but then use those layers within arcpy geoprocessing tools?

Thanks,

Nikholai

Some additional notes to your comments on:

"including arcpy scripts for redeploying server instances, publishing services, ingesting data to RDBMS"

Publishing Services:

* Assuming you are using REST to publish and manage services to ArcGIS GIS Server, your workflows would still need to be done via arcpy. 
* ArcGIS Python API only supports publishing services to Portal for ArcGIS or ArcGIS Online
* publishing SDs shapefiles and CSVs | ArcGIS for Developers 
* publishing web maps and web scenes | ArcGIS for Developers

Redeploying Server Instances:

* If you are referring to managing services or perform administrative processes of ArcGIS GIS Server, that functionality does not exist in the ArcGIS Python API
* The main use of the ArcGIS Python API is for Portal for ArcGIS and ArcGIS Online

Ingesting Data to RDBMS:

* ArcGIS Python API has no DBMS capabilities
