Check Confluence Attachment Migration

[김광일]

There is a way to do the entire space during migration with Confluence migration assistat and a way to send only attachments.
When only attachments are migrated, Cloud Confluence
Is there a way to check that the attachments have been migrated?

I haven't performed an attachment-only migration myself as yet but could you create a backup of the Cloud site with attachments and compare it with size of attachments on the local site?

There's probably a better way of knowing (API, audit log, data center/server logs and so on) but the backup should work as an alternative.
