The Management Reporter cumulative updates (CU) no longer contain the Migration Wizard. The last CU that contains the Migration Wizard is 2.12.16009.1. The Migration Wizard that comes with the 2.12.16009.1 is not compatible with the later Management Reporter releases. If you need to use the Migration Wizard, install the Management Reporter release 2.12.16009.1 and run the migration process. After doing this, uninstall Management Reporter and upgrade to the latest Management Reporter release.
