When you migrate SAS Enterprise Miner from a 32 bit operating system to a 64 bit operating system, or when you move projects to a different operating system platform (for example, Windows to UNIX, Windows to Linux), you must take steps to ensure that the projects will open correctly on the new system. This note is written for Windows 32 bit to Windows 64 bit conversion, however the same steps and logic apply for other operating system changes.

If you move the project from one operating system platform to a different one and try to open a diagram within the project you will receive this error:

exception.server.WORKSPACE.COULDNOTOPEN,EMWS.EM_DGRAPH 
in SASHELP.EMCORE.PROJECT.SCL at line 1424 from server method invoke.

The following process has 3 separate copies of the project:

• original project - kept as a backup and not deleted until migration is validated
• temporary copy of the original project - used to package data and catalogs for transport
• original project copied to the new location - cleared of old data, views and catalogs to retain project architecture

The attached document outlines the steps.

SAS Enterprise Miner 6.1 M3 or later

If you are running SAS Enterprise Miner 6.1 M3 or later, then you can use a migrate project tool that replaces some of the manual steps. (Go to Help ► About from within the SAS Enterprise Miner client to show the version that you are running.) To access the migrate project tool, go to Enterprise Miner Migrate Project.
