Uninstall Data Migrator

info

An optional step detailed below in the section Uninstall Data Migrator is to delete all Data Migrator directories.
These directories contain user-modified files such as configurations, logs, and backups that you may want to keep.
Archive the directories if you want to keep backups and configurations.
