What places should i change in Cognos in case i replace my Microsoft SQL database host to a new server?

Stop all Cognos windows services.
Take a backup of the databases and copy them over to the new database server.
Ensure that the collation settings (sort order) is the same on old and new database instances.
Ensure that the SQL login have the correct dbowner rights on the database tables.

Cognos BI have connections to content store, and other databases you have setup from Cognos Configuration.
Start Cognos Configuration.
Go to Environment – Logging – Audit – Audit and change database server with port numbers value to the new SQL server.
Go to Data Access – Content Manager – Content Store, and change database server name value to the new SQL server.

Repeat the change for notification database,and any other database you have setup in Cognos configuration.
Save the changes and start the CA11 services, in case you have more than one BI server, start with the primary content manager first.

Surf to Cognos Connection, go to manage – administration console. Click on configuration tab. Go to Data Source Connections and in the right side click on the database link name. Then click on more in the right side.

Go to Enhanced Reporting Optimizations tab – change the server name here. In most cases the file share for the ERO function is on the SQL server, and therefor need to be changed when you change your database server. Click save after each change, and you need to update each connection.

Ask the cognos controller users to test, by run a excel report with the ERO function active.

If the ERO share is on a file server (or the cognos controller server) you need to add the windows service account that the new SQL server is using to the file share, so the SQL server process have access to the files in this share.

The FAP service is configured in the C:\Program Files\ibm\cognos\ccr_64\server\FAP\ file. Open it in notepad++.
