From codeBeamer-10.0, it is ensured that all uploaded files/attachments - depending on their calculated SHA-512 code - exist physically only once, all duplicates just get a link to the already existing file/blob. This one time calculation for all already existing files/blobs is time consuming thus the Upgrade procedure to 10.0 can take several hours depending on the stored Documents in storage. It is highly recommended to schedule upgrade processes during the Weekend.
codeBeamer has a known limitation of previously removed and unsupported Approval Workflow feature during upgrade procedure, these symptoms will be addressed with manual processes
