These are just informative messages and doesn't necessarily indicate any issues with the upgrade process. Based on what message is displayed, Spotfire Administrators must take necessary actions (example: copying any 3rd party JDBC drivers to the upgraded version) to complete the upgrade.

For example, in the screenshot above:

- The first message shows that Spotfire 10 and above only supports Apache Ignite clustering. If you had a different clustering enabled in your previous version, like Hazelcast, the configuration will be automatically upgraded to use Apache Ignite in the upgraded version.

- The second message shows the change in the data source template for Amazon Redshift JDBC Data Source. In versions earlier to 10.x, the "connection-url-pattern" field for Amazon Redshift data source template used to be as the one below:
=====
<connection-url-pattern>jdbc:postgresql://&lt;host&gt;:&lt;port&gt;/&lt;database&gt;?tcpKeepAlive=true</connection-url-pattern>
=====

This field has now been changed as below, in Spotfire 10 and later versions.
=====
<connection-url-pattern>jdbc:redshift://&lt;endpoint&gt;:&lt;port&gt;/&lt;database&gt;</connection-url-pattern>
=====

So, the "Connection URL" for Amazon Redshift data source should start with "jdbc:redshift://" as shown below.

- The third message shows that the Oracle JDBC driver(ojdbc jar file) that was in use in the previous version should be copied to [Installation Directory/tomcat/webapps/spotfire/WEB-INF/lib/]

Note: If you are upgrading to Spotfire version 10.3, any 3rd party JDBC drivers from the previous versions will be copied by the upgrade tool itself.
