Upgrade and Enhance Parcel Management application and Migrate Esri ArcGIS Enterprise to version 10.8.1.
Cook County hired Esri as the Prime contractor in 2013 to create the PINMAP application, as the next generation of the parcel management application that was originally built by Esri (and updated/migrated by Great Arc several times) 15 years prior. Great Arc Technologies, as subcontractor to Esri, built the web-based portion of the PINMAP application between the fall of 2013 and the fall of 2015.
This system manages over 1.9 million parcels in addition to lots, rights-of-way, subdivisions, and other property-related features. The system was deployed in an Esri 10.2.2 environment including ArcGIS Enterprise, ArcGIS Workflow Manager and ArcGIS Desktop. Cook County decided to upgrade its entire ArcGIS Enterprise environment, including the PINMAP application, to take advantage of new features and technologies in Esri's latest version as well as include enhancements to the PINMAP application.
Great Arc was selected to manage the PINMAP application upgrade, including many application enhancements, along with the Esri Enterprise version upgrade. As a vital system for the County, Great Arc developed a plan for a rapid transition from Esri 10.2.2 to 10.8.1 to minimize system downtown.
To simulate the application and environment migration, Great Arc configured replica ArcGIS Enterprise 10.2.2 and 10.8.1 environments. These were used to test the migrated and upgraded PINMAP application, identify compatibility issues, as well as define the final migration plan.
Throughout the development process, Great Arc helped Cook County install and configure the ArcGIS Enterprise 10.8.1 and ArcGIS Desktop 10.8.1 clients for both the Test/Staging environment and new Production environment.
Upon completion of the PINMAP application upgrades and final Cook County environment configuration, Great Arc helped completed the final migration from their production 10.2.2 environment to the new 10.8.1 by executing a set of predefined scripts defined and tested in the Great Arc replicated environment. This allowed for a fast migration with minimal user downtime.
