ZSD ZENworks Integration failing to connect after Database Migration

ZSD ZENworks Import configured to the ZCM 2017 Internal Sybase Database.

ZCM 2017 internal Sybase database is migrated to internal PostgreSQL.

Modifying the ZSD ZENworks Import db parameters doesn't seem to work.

      User > Configuration > Categories > Hardware (or mobile Devices)
Select a field that would be unique in the Label column like "Serial Number" (commonly used)
Check the box as a Unique Value
Then on the Categories > Hardware area populate the Reconcile Based On drop down to that Unique field (Serial Number).

Manually reconfigure the new ZENworks Database Integration settings.
Setup > ZENworks > ZENworks Import | select the Server
Modify

   Type: PostgreSQL

   Port: 54327
   Name: (same name - all lowercase)    -   Example if used zenworks_ZENZONE, change to zenworks_zenzone
   Password: (new db password by executing a zman dgc)

Do not delete and re-add the Import Server or Item duplicates can occur!

If you reconfigure by deleting the ZENworks database by the following options below,

duplicate Items will be created UNLESS the Item Reconciliation enabled for that Item (Hardware or Mobile Devices).

Configure ZSD ZENworks Import server to connect to the new PostgreSQL database

Delete the ZENworks Import Server

    ZSD > Setup > ZENworks > General
Authtenticate to the ZENworks Server Settings > Save

No ZENworks Import has the updated information to connect to the PostgreSQL database.

Or
Delete the ZENworks Import Server

Select "Getting Started" wizard and start the ZENworks Integration.
