What is NIEM Migration Assistance Tool?
The NIEM Migration Assistance Tool is an easy tool for you to migrate your current wantlist to the lastest version. The Migration Tool is a tool that allows you to upload your wantlist file that you find in an IEPD, and generate the ouputs for you in just a click of a button. The outputs should include a new migration wantlist, a new subset, and a migration report that indicate the status of that migration resolution.
Here are the supported levels of the tool:
Notice: If you have a wantlist file version NIEM 2.1 and you want to upgrade to the latest version which is NIEM 3.0-with-domain-updated, the tool will migrate the file into the NIEM 2.1-with-domain-updated first, and you will take this wantlist file verison NIEM 2.1-with-domain-updated and continue upload to migrate to the next version. You need to repeat this step until you have the latest wanlist, the latest subset, and the status report.
