# 15C Working Conversation

Me: Before changing the database structure, could you export the current data and explain exactly which files and records the backup will contain?
Developer: The database export will contain the records, but uploaded images are stored separately, so their files require a separate backup or reference.
Me: Please record the source environment and date, and keep the backup in a location appropriate for the private information that it contains.
Developer: I will also describe the restore procedure, including which services must be available and whether restoring will replace any existing records.
Me: Have the learner progress and saved vocabulary been included, or does the export cover only the public course content that visitors can read?
Developer: Both are included in this export; I will list the relevant tables so that the scope is explicit rather than assumed.
Me: Good; after the migration, check whether the application can still read the old records and open the files associated with them.
Developer: I will report which data has been preserved and identify any resource that remains outside the backup or depends on a separate system.
