The following explains how to move the Pyramid repository location to another server if needed.

You first need to stop the services to change your Pyramid repository location.
Then back up your Database and restore it to the destined server.

For each Pyramid server in your deployment edit the config.ini file. Update "Dbhost" to point to the new repository server (see picture).

By default it can be found here c:\Program Files\Pyramid\config.ini and on Linux  /opt/Pyramid/config.ini

If the username and password  will stay the same, there is no need to do anything else. Otherwise, you will need to update the config.ini file with the new user and encrypted password(this applies if only one of them will change).
To accomplish it, follow this article: How to update the Pyramid repository credentials.
