We are migrating from cloud instance to server and as part of the import attachment process, manually copied files to JIRAHOME/data/attachments folder. Due to some reason not all files were copied and as a result the attachments are missing in the new instance. Below is the log from import process (used Configuration Manager to deploy a snapshot from staging server).
I am having trouble finding ways to import these missing attachments to new instance. Tried copying the physical files to default location and restarted JIRA hoping it would magically pick them up from the file system but no luck. What are my options here.
