Configure Recast RCT has no SQL tab

When opening the Configure Recast RCT there is no tab for SQL. Is there anyway to get this, or even access database configuration without it? We are in the process of moving the Databases to another server and the documentation I have found online says it should be done through this.

Unfortunately the person who installed the product has left the company

Sounds like you are using the Recast Management Server (RMS). The SQL information will be located in the RMS portal under Settings > Settings. The web address for the RMS is located under the Configure Recast RCT - RCT Enterprise Server.
