Attachment migragtion from v4 to v3 storage

[Dmitri Bukovski]

Hi, has anybody tried to export attachments from v4 storage to an older v3?

We have a couple of Confluences with different versions - 8.6 and 7.13, and we noticed that after we exported content from 8.6 to 7.13 the attachments seem to be missing - they can be seen in the attachments section, but none of them available. If we manually add the attachment from 8.6 content to the counterpart page of 7.13 preserving the name, the attachment becomes available in the Attachments menu, but it is not displayed on the page.

I've read that these versions have different approaches to attachment storage and there was a guide on transition from v3 to v4, but is there a way to do a backwards transition?

I think you found the backward approach, you need to add the content to the 7.13 version of the page.
