Transfer of media from JIRA server to cloud

[abhay.krishnau.ext@hmdglobal.com]

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.

Hi Abhay,

welcome to the Atlassian Community!

I am not aware of any further tricks than that what is in the documentation. One option would be to do a cleanup - to just import what is really needed anymore.

Probably by doing so you can reduce the amount of data by some TB?

Cheers,
Daniel

Hi Daniel,

Thanks for replying. 

So it looks like while using cloud site import there is no other easier way to import large volume of attachments from Server to Cloud.

Even if we do a bit of clean up, there would still be around 6-7 TB of attachments files to migrate to the cloud site.

At least I am not able to see such a limitation mentioned in the documentation if we are using the JIRA cloud migration assistant instead of the Cloud site import. 

We are currently performing a test migration in our lower environment and since we have to move all the project data and attachments entirely from our JIRA server instance to the cloud site, we thought initially that the cloud site import would be a much easier option.

But due to the need for diving such a large volume of attachment data to smaller chunks, I guess the cloud migration assistant would be a better option.

Then, this option has also has its limitations like it will not import certain types of custom fields. And we have large number of projects, custom fields and field contexts, that we would have to manually recreate and add them which would again turn into a hectic, complicated task.

Anyways thanks for your comments. I hope we would be able to find some simpler solution during our trial migration.
