Backporting is the process of porting a software update that was developed for a relatively current version of a software entity, to an older version of the software. It is a maintenance activity of the software development process. Although a backported update can modify any aspect of the software, the technique is typically used for relatively small scope changes such as fixing a software bug or security vulnerability.
向後移植是一種對現有软件進行更改（修補程式）的動作，其將較新版本的改變部份移植到舊版軟體上。它構成了软件开发过程中的軟體維護步驟，通常用於修復舊版軟體中的安全性錯誤。
