如何强制 Prestashop 1.4 尾部斜杠升级到 1.6

我有一个旧的Prestashop 1.4安装，页面没有尾部斜杠。示例：domain.com/category

我想升级到新版本的 Prestashop （1.6）此版本强制使用尾部斜杠（例如：domain.com/category/），理由充分。问题是我不想在任何搜索引擎中失去我的任何排名。

因此，我想做的是配置我当前 1.4 安装的 .htaccess，以便强制使用尾部斜杠并正常工作，因为现在它将导致 404。

这是.htaccess，即使在阅读了几篇有关重定向等的博客之后，我也不知道从哪里开始。谁能帮助我或提供建议？
