Issues while migrating nintext databases to new farm (SP 2013 on prem)

[#1]

We are trying to migrate Nintex from SharePoint online dedicated to SP 2013 on premise  and below are the steps we followed

1. We received 2 databases (config and content) from SharePoint online dedicated

2. We have restored both the databases on SQL server

3. In config database, we have found a table "databases" which has currently two entries/records (both the entries are showing config and content databases)

4. when we tried to attached config database using central admin - "Nintex Workflow Management" --> "databse Setup" --> Configuration Database, we got error - object reference not initialize

5. To resolve the issue in step #4, we have deleted two entries from "databases" table of config database (mentioned in  #3 )

6. Using central admin, we have attached content database by link Add content database,

7. After step #6, we have checked "databases" table of config database where we found 1 entry/record

Here are my questions,

1. How can we add second entry into the  "databases" table in #3

2. Can we attach config database as a content databases

3. Can we restore the config database again with different name and attached it as a content database

It would be really appreciable fi you could provide answers for above questions and best practice document for these scenario

Thanks,
