Confluence has been updated to version 6.15.9

The maximum attachment size that you can synchronize depends on a couple of factors:

  • the attachment size limit on both instances (you can configure the max attachment size in Jira)
  • instance HTTP/HTTPS connection timeouts

We’ve tested the synchronization of attachments with the size up to 1 GB and it worked without any issues.

Also, bigger attachments should not be a problem either.
