The company I work for is currently going through a lot of changes, one of which is the decommissioning of a server that contains all attachments for BCM Remedy tickets. Before doing so though, I was tasked with migrating (and archiving) those attachments to SharePoint Online, and so I'm currently researching which method out there would be most ideal.
For each ticket (roughly 80k of them), there's just the ticket # and then a collection of attachments (multiple attachments for a single ticket is quite prevalent); they are comprised of all kinds of file types. As time goes by, these tickets will be accessed less and less, and are actually barely accessed even now, as is.
The two methods I'm considering for storage and retrieval of these attachments is either a Document Library or an Item List. My question is: which of these would be better for pure storage and retrieval? The only criteria that will be used to search for a ticket is the ticket #.
Thanks in advance!
