Requirements for Upgrading to erwin Data Modeler release 2020 R2

Requirements for Upgrading to erwin DM 2020 R2 

Standard and Workgroup 

When upgrading from an earlier version of erwin Data Modeler (DM) to the current (2020 R2) version, please make sure that there are enough resources required to make the transition as smooth as possible.  Here are the specifications as defined in the Release Notes. 

Operating System Support 

To run erwin Data Modeler it is recommended that you have the latest version of one of the operating systems (32-bit or 64-bit) installed: 

• Microsoft Windows 8.1
• Microsoft Windows 10
• Microsoft Windows Server 2012, R2
• Microsoft Windows Server 2016
• Microsoft Windows Server 2019

Note: As a best practice, always upgrade your operating system to its latest available version. 

erwin Data Modeler 32-bit (these notes do not apply to the 64-bit version of erwin Data Modeler) is fully compatible with 64-bit operating systems, except for the following known issues: 

• 64-bit database drivers and clients will not work with erwin Data Modeler 32-bit. The workaround is to use 32-bit database drivers and clients even if running in the 64-bit operating system environment.
• Running the erwinData Modeler 32-bit API in a 64-bit environment requires some changes to the workstation registry. For more information about changing the registry, see the erwin Data Modeler Workgroup Edition Implementation and Administration Guide.
