Hi team

Thank you so much

Gilbert ,

When I migrate since 8.4.2 to next LTS version ( 8.9.3) appear the following error

Do you have any idea what could be happening to me?

The migration path is right, see Before You Upgrade | SonarQube Docs
The IndexFormatTooNewException means it tries to read data written with another major version of Elasticsearch and Lucene.
Did you try a direct update from 8.4.2 to 9.1.0 at first by mistake ?
Look if there is a folder $SONARQUBE_HOME/data/es7
If yes, delete it and retry the update from 8.4.2 => 8.9.3 => 9.2.1 (you should use either the LTS or the
latest version of Sonarqube = 9.2.1)
