Issue Summary

Confluence v1 Copy Page API {{POST /rest/api/content/{id}/copy }}when used with

• destination.type = "existing_page"

• copyAttachments = true

It creates a new version of every attachment on the destination page, even when the source attachment has not changed and is expected to be identical.

Steps to Reproduce

1. Create source page A
2. Upload image.jpg to A
3. Copy A to create destination page B using Copy Page API with copyAttachments=true
4. Confirm image.jpg on B is at version v1
5. Do not modify image.jpg on A
6. Copy A again using:
7. destination.type = "existing_page"
8. destination.value = B_ID
9. copyAttachments = true
10. Check image.jpg on B

it becomes v2 even though the source file was unchanged.

Expected Results

If the attachment already present on the destination matches the source attachment (same filename, same content), either skip it or keep the existing version. Only produce a new version when the original page also produced a new version.

Actual Results

Every copy creates a new version of attachments

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
