This past weekend we migrated our production environment from JIRA 6 to JIRA 7 however, the attachments/images were not migrated over. We are missing about 2 months worth of attachments in our JIRA 7 environment. How can we migrate over a subset of attachments?
We have already tried copying a folder containing the missing attachments, re-indexing, and restarting the JIRA services. This did not work.
