How do I export/import issue attachments from one Jira On Demand to another Jira OD implementation

[Chuck]

We are merging companies and we both have Jira On Demand.  I can get the fields to come over but the attachments seem to be getting corrupted in transit.  There are no errors in the import log and the file names, dates, etc. look correct but I cannot open them in the destination system.  These are .png files.

Hello,

How do you try to export and import data? Do you use the backup/restore or export/import csv file feature?

The export/import feature.

Then you should use Jira rest api to move attachments. You could import attachments from Jira Cloud to Jira on-prem using standard export/import. But for Cloud is not available.
