ISSUE
When accessing Setup Database in Central Administration, after a migration has been performed, the following error might occur:Object reference is not set to an instance of an object.
RESOLUTION
- Run the stored procedure (Programmability > Stored Procedures) "dbo._PrepareForNewEnvironment", this will purge references to the previous SQL server.
- In Central Administration > Nintex Workflow Management > Database Setup, add the new content databases, please ensure that the "connect to an existing database" check box is selected.
