Download Enterprise Binaries下载企业二进制文件
Depending on your operating system, you can install the MongoDB Enterprise binaries by using a package manager or by downloading the binaries manually.根据操作系统，您可以使用包管理器或手动下载二进制文件来安装MongoDB Enterprise二进制文件。
Linux(Package Manager)
If you have installed MongoDB Community using a package manager, follow the package manager instructions for your operating system:如果您使用包管理器安装了MongoDB Community，请按照操作系统的包管理器说明进行操作：
During the installation, the package manager will remove the community packages; this will not affect the running deployment until you restart.在安装过程中，包管理器将删除社区包；在您重新启动之前，这不会影响正在运行的部署。
Linux(Manual Download)
If you have not installed MongoDB using a package manager, you can manually download the MongoDB binaries from the MongoDB Download Center. 如果你没有使用包管理器安装MongoDB，你可以从MongoDB下载中心手动下载MongoDB二进制文件。Follow the manual instructions, including specific prerequisites for MongoDB Enterprise, for your operating system:遵循适用于操作系统的手册说明，包括MongoDB Enterprise的特定先决条件：

Procedure过程
To minimize downtime, you can upgrade from MongoDB Community to Enterprise Edition using a "rolling" upgrade by upgrading the members individually while the other members are available.为了尽量减少停机时间，您可以使用“滚动”升级从MongoDB社区升级到企业版，方法是在其他成员可用的情况下单独升级成员。
Upgrade secondary members of the replica set.升级副本集的辅助成员。
Upgrade the secondary members of the replica set one at a time:一次升级一个副本集的辅助成员：
Shut down the关闭mongodinstance.mongod实例。Restart with the Enterprise使用Enterprisemongod, specifying the same configuration options (e.g. same data directory, configuration file, etc.).mongod重新启动，指定相同的配置选项（例如，相同的数据目录、配置文件等）。
Wait for the member to recover to 在升级下一个SECONDARY state before upgrading the next secondary member.SECONDARY成员之前，请等待成员恢复到SECONDARY状态。
Step down the replica set primary.逐步关闭主副本集。
Once all the secondary members have been upgraded to Enterprise, connect 一旦所有次要成员都升级到Enterprise，将mongosh to the primary and use rs.stepDown() to step down the primary and force an election of a new primary.mongosh连接到主要成员，并使用rs.stepDown()退出主要成员并强制选举新的主要成员。
Upgrade the primary.升级主服务器。
When 当rs.status() shows that the primary has stepped down and another member has assumed PRIMARY state, upgrade the stepped-down primary:rs.status()显示主服务器已降级，另一个成员已处于primary状态时，升级降级的主服务器：
Shut down the stepped-down primary.关闭已降级的小学。Restart with the Enterprise使用Enterprisemongod, specifying the same configuration options (e.g. same data directory, configuration file, etc.).mongod重新启动，指定相同的配置选项（例如，相同的数据目录、配置文件等）。
Important
Before using any Enterprise features, ensure that all members have been upgraded to Enterprise edition.在使用任何企业版功能之前，请确保所有成员都已升级到企业版。
