Abstract: A network-based solution for automatically processing large email attachments or other files during migration between email platforms or other platforms, as may be embodied by various systems, methods, and non-transitory computer-readable storage media, may involve downloading mailboxes from a source email platform and inspecting the mailboxes for emails containing attachment files. The solution may involve determining a file size of any detected attachment, comparing the file size of the detected attachment file to a predetermined attachment size limit, and uploading a copy of the detected attachment to a storage server for storage when the comparison determines that the file size of the detected attachment file exceeds the predetermined attachment size limit. The solution may further include modifying the email by replacing the detected attachment with a link to the copy of the detected attachment stored at the storage server and then migrating the modified email to the target email platform.

Abstract: In one embodiment, a method includes serializing a data set into a binary package. The serializing includes, for each element of the data set, determining whether the element includes a predefined multi-bit element value. The serializing further includes encoding a lead byte comprising a data-type identifier and a value indicator. Responsive to a determination that the element includes the predefined multi-bit element value, the encoding of the lead byte comprises setting the value indicator to a preconfigured indicator of the predefined multi-bit element value, the preconfigured indicator requiring fewer bits to represent than the predefined multi-bit element value. Responsive to a determination that the element does not include the predefined multi-bit element value, the encoding of the lead byte comprises setting the value indicator to a preconfigured value-follows indicator.
