from 8.2 to 9.0. Prepared migration concepts, executed upgrade procedures, and
validated compatibility of reports and configurations. Resolved technical issues
arising during the upgrade process and ensured stable operation across EMSA?s
environments. Conducted regression testing and coordinated deployments in
close collaboration with operations teams.
In addition to the upgrade activities, continuously monitored the stability of the
reporting infrastructure. Took proactive measures to prevent outages, identified
and analyzed issues when they occurred, and applied corrective actions to
restore system reliability and ensure uninterrupted service for end users.
