I am trying to migrate keycloak from 11 to 16.1.0 and fails with, the following error ... I have removed all smallrye entries in standalone.xml, how can I see a more detailed error message?
the migration is run via
bin/jboss-cli.sh --file=bin/migrate-standalone.cli
*** WARNING ***
** If the following embed-server command fails, manual intervention is needed.
** In such case, remove any <extension> and <subsystem> declarations referring

** For details, see Migration Changes section in the Upgrading guide.
** We apologize for this inconvenience.
Cannot start embedded server: WFLYEMB0021: Cannot start embedded process: JBTHR00005: Operation failed: WFLYSRV0056: Server boot has failed in an unrecoverable manner; exiting. See previous messages for details.
I have the same problem, upgrading from 15.0.2 to 16.1, standalone mode + external MySQL database.
#EDIT
I've found this... - https://www.keycloak.org/docs/latest/upgrading/#migrating-to-16-0-0
Due to the amount of changes we are not able to provide migration scripts as we have done in the past.
We recommend that rather than copying configuration files from previous versions of Keycloak that you start with the default configuration files provided in Keycloak 16 and apply the relevant changes.
