# 将社区版MongoDB升级到企业版MongoDB

MongoDB企业版提供了MongoDB社区版中未提供的各种功能，例如：

* [内存存储引擎](https://docs.mongodb.com/v4.2/core/inmemory/)
* [审计](https://docs.mongodb.com/v4.2/core/auditing/)
* [Kerberos身份验证](https://docs.mongodb.com/v4.2/core/kerberos/)
* [LDAP代理身份验证](https://docs.mongodb.com/v4.2/core/security-ldap/)和[ LDAP授权](https://docs.mongodb.com/v4.2/core/security-ldap-external/)
* [静态加密](https://docs.mongodb.com/v4.2/core/security-encryption-at-rest/)

本部分中的文档提供了从社区版MongoDB升级到企业版MongoDB的说明。

重要

不要使用这些说明升级到另一个发行版本。要升级发行版本，请参阅相应的发行升级说明，例如[Upgrade to MongoDB 4.2](https://docs.mongodb.com/v4.2/release-notes/4.2/#upgrade)。
