After upgrading CA Service Desk Manager from 12.9 to 17.1, although we are able to open ticket attachments that were created after the upgrade, when attempting to open ticket attachments that existed before the update, the following error is returned:
HTTP Status 400 - Wrong redirection type Status report message Wrong redirection description The request sent by the client was syntactically incorrect. Apache Tomcat/8.5.6
The content of the "attachments" subdirectory under $NX_ROOT\site was moved out from under $NX_ROOT before you ran the installer and all of the files were not restored.
CA Service Desk Manager 17.1
Check that the attachments folders that exists in the pre-upgraded system are in sync with the folders in the upgraded system. Copy anything that is missing from your pre-upgrade archives or snapshot.
