we're going to start with Jira Datacenter after having used Jira cloud. So we have to get all jira cloud data . We've experimented the system backup procedure but it doesn't include attachments. How could we get them ?
I suspect you'll need to ask the cloud folks for assistance. On the server side you need access to the server and folder the attachments are in. I doubt you have that type of access in cloud. When I've moved a server instance I've copied the folder from the old to the new server and pointed the config file to the new location.
You should check out the answer provided here:
I'm also on Cloud and can confirm that the Backup manager on Cloud has a version for for Cloud backup as well as "Back up for Server" with a checkbox to include attachments, avatars and logos.
That is what you will want to use if you are moving to Data Center.
