Merging files must move existing files in S3 and rewrite path in x_opencti_files

[richard-julien]

Description

When entities are merged, x_opencti_files are accumulated directly in the target. However as the x_opencti_files are stored in a path that contains the internal_id of the element, this merging doesnt do the right operations. Merging process must be improved to:

• Move the files in the S3/Minio to the target entity
• Rewrite the x_opencti_files sources to comply to the new path

Hints

Metadata of the file in s3 can be discarded are no longer used.

@richard-julien I could not reproduce by uploading a file in an entity and merging the entity with another one.

Could you detail the steps to reproduce and the expected output?
