We have a JIRA server instance with the attachment folder size of over 8.9 TB.
We are planning to eventually migrate from JIRA server to atlassian cloud. In the migration document, I am able to see that the attachments should be divided into files of 2-5GB in size for importing them to the cloud site using site import.
Since we have around 8.9 TB of data comprising of around 350k individual attachment files, how can we import such a large volume of media from Server to Cloud.
