This article provides brief information on the following error:

NCM Database migration failed.

Exception of type 'System.OutOfMemoryException' was thrown 


NCM, all versions


The issue is caused by large DB size and ConfigArchive table stored the device configs for more then 30 days for many devices. 



See the following guide:

Quick Orion database health check guide

Manually remove device configs from the Config Archive tables and then shrink the DB worked.
