# Migriert eine bestehende SuperX-Installation in eine neue Tomcat-Webapp-Struktur.
#
# Erwartete Dateien im selben Verzeichnis:
# migrate_superx.conf
# migrate_superx_webapp.sh
#
# Modi:
# MIGRATION_MODE=full
# Webapp wird nach TARGET_WEBAPP kopiert.
# db wird nach TARGET_WEBAPP/WEB-INF/conf/edustore/db kopiert oder verschoben.
#
# MIGRATION_MODE=db_only
# Webapp wird nicht kopiert.
# db wird in die bestehende oder angegebene Webapp unter WEB-INF/conf/edustore/db kopiert oder verschoben.
#
# DB_TRANSFER_MODE:
# copy: db wird per rsync kopiert.
# move: db wird per mv verschoben. Ziel-db darf dabei noch nicht existieren.
# Migriert eine bestehende SuperX-Installation in eine neue Webapp-Struktur.
# Standardziel: /home/superx/webapps/superx
# Optional: Symlink aus Tomcat-webapps auf TARGET_WEBAPP.

Migration abgeschlossen.
Naechste sinnvolle Pruefungen:
Pruefen:
ls -ld " $TARGET_WEBAPP "
ls -ld " $TARGET_DB "
ls -l " $TARGET_DB /bin/SQL_ENV "
Neue SQL_ENV laden:
. " $TARGET_SQL_ENV "
Pruefen:
echo \$ SUPERX_DIR
echo \$ WEBAPP
umask
Hinweis:
Falls der Tomcat-User neu zur Gruppe '$SUPERX_GROUP' hinzugefuegt wurde,
muss Tomcat neu gestartet werden, damit die Gruppenrechte greifen.
