Some time ago i wrote article about migration from Wildfly 10 to Wildfly 18 and application level migration issues. Migration from Wildfly 18 to Wildfly 20 does not provoke any application level issues and can be done in minutes:
git clone https://github.com/wildfly/wildfly-server-migration.git
cd ./wildfly-server-migration/
mvn clean install
cd ./dist/standalone/target/
unzip jboss-server-migration-1.10.0-SNAPSHOT.zip
cd ./jboss-server-migration
./jboss-server-migration.sh -s /opt/wildfly-18.0.0.Final -t /opt/wildfly-20.0.1.Final/
Why should i do migration to Wildfly 20 ?
