更改现有 Azure Active Directory 域服务托管域的 SKUChange the SKU for an existing Azure Active Directory Domain Services managed domain

在 Azure Active Directory 域服务 (Azure AD DS) 中,可用的性能和功能基于 SKU 类型。In Azure Active Directory Domain Services (Azure AD DS), the available performance and features are based on the SKU type. 这些功能差异包括备份频率或单向出站林信任的最大数量。These feature differences include the backup frequency or maximum number of one-way outbound forest trusts.

创建托管域时,你可以选择一个 SKU,并且可以在部署托管域后,根据业务需求的变化上下切换 SKU。You select a SKU when you create the managed domain, and you can switch SKUs up or down as your business needs change after the managed domain has been deployed. 业务需求的变化可能包括需要更频繁地备份或创建其他林信任。Changes in business requirements could include the need for more frequent backups or to create additional forest trusts. 若要详细了解不同 SKU 的限制和定价,请参阅 Azure AD DS SKU 概念Azure AD DS 定价页。For more information on the limits and pricing of the different SKUs, see Azure AD DS SKU concepts and Azure AD DS pricing pages.

SKU 更改限制SKU change limitations

部署托管域后,可以向上或向下更改 SKU。You can change SKUs up or down after the managed domain has been deployed. 但是,如果使用资源林并且已创建从 Azure AD DS 到本地 AD DS 环境的单向出站林信任,则 SKU 更改操作会有一些限制。However, if you use a resource forest and have created one-way outbound forest trusts from Azure AD DS to an on-premises AD DS environment, there are some limitations for the SKU change operation. 高级和企业 SKU 定义可创建的信任数量限制 。The Premium and Enterprise SKUs define a limit on the number of trusts you can create. 无法将其更改为最大限制低于当前配置的 SKU。You can't change to a SKU with a lower maximum limit than you currently have configured.

例如:For example:

  • 如果已在高级 SKU 上创建了两个林信任,则无法将其向下更改为标准 SKU 。If you have created two forest trusts on the Premium SKU, you can't change down to the Standard SKU. 标准 SKU 不支持林信任。The Standard SKU doesn't support forest trusts.
  • 或者,如果已在高级 SKU 上创建了七个林信任,则无法将其向下更改为企业 SKU 。Or, if you have created seven trusts on the Premium SKU, you can't change down to the Enterprise SKU. 企业 SKU 最多支持五个信任关系。The Enterprise SKU supports a maximum of five trusts.

若要详细了解这些限制,请参阅 Azure AD DS SKU 功能和限制For more information on these limits, see Azure AD DS SKU features and limits.

若要使用 Azure 门户更改托管域的 SKU,请完成以下步骤:To change the SKU for a managed domain using the Azure portal, complete the following steps:

  1. 在 Azure 门户的顶部,搜索并选择“Azure AD 域服务”。At the top of the Azure portal, search for and select Azure AD Domain Services. 从列表选择托管域,例如 aaddscontoso.com。Choose your managed domain from the list, such as aaddscontoso.com.

  2. 在 Azure AD DS 页左侧的菜单中,选择“设置”>“SKU”。In the menu on the left-hand side of the Azure AD DS page, select Settings > SKU.

    在 Azure 门户中为 Azure AD DS 托管域选择 SKU 菜单选项

  3. 从下拉菜单中,选择希望用于托管域的 SKU。From the drop-down menu, select the SKU you wish for your managed domain. 如果有资源林,则不能选择标准 SKU,因为林信任仅在企业 SKU 或更高版本上可用 。If you have a resource forest, you can't select Standard SKU as forest trusts are only available on the Enterprise SKU or higher.

    从下拉菜单中选择所需的 SKU,然后选择“保存”。Choose the SKU you want from the drop-down menu, then select Save.

    从 Azure 门户的下拉菜单中选择所需的 SKU

更改 SKU 类型可能需要一两分钟的时间。It can take a minute or two to change the SKU type.
