概述

有两种自动方法可用于执行版本回滚，以恢复到旧的 IncrediBuild 版本：快速回滚和完全回滚。

准备阶段

1. 确保您可以从运行 IncrediBuild Coordinator的计算机访问旧的 IncrediBuild 版本的安装应用程序。
2. 确保所有 IncrediBuild Agents都已连接到Coordinator，并且用户已登录到这些计算机（脱机Agents可以在稍后手动更新）。
3. 确保您的许可证文件已准备就绪。
4. 通知所有 IncrediBuild 用户即将进行版本回滚，利用Coordinator“Send Message...” Agent菜单选项。

方法 1 - 快速回滚

使用此方法，旧版本将安装在当前的新版本之上。 这种回滚方法保留了现有的配置，是最快捷、最简单的方法。 但是，由于在安装旧版本之前未完全卸载新版本，因此存在留下不受支持的文件或数据的风险，特别是在回滚到非常早期的版本时。 如果发生这种情况，可以使用“Full Rollback”选项来更正条件（见下文）。

注意:

• 在回滚Coordinator计算机之前，必须在远程Agents上执行回滚。

要执行快速回滚：

Overview

Two automated methods are available for performing a version rollback in order to revert to an older IncrediBuild version: Quick Rollback and Full Rollback. 

Preliminary Steps

1. Make sure the older IncrediBuild version's Setup application is accessible from the computer running IncrediBuild Coordinator.
2. Make sure all IncrediBuild Agents are connected to the Coordinator, and that a user is logged on to these computers (offline Agents can be updated manually at a later time).
3. Make sure your license file is ready.
4. Notify all IncrediBuild users about the upcoming version rollback using the Coordinator "Send Message..." Agent menu option.

Method 1 – Quick Rollback

With this method, an older version is installed on top of the current newer version. This method of rolling back maintains the present configuration and is the quickest and simplest method. However, because the newer version is not fully uninstalled before the older version is installed, there is some risk of leaving behind unsupported files or data, in particular when rolling back to a very early version. Should this happen, it is possible to correct the condition using the 'Full Rollback' option (see below).

Note:

• Rollback must be performed on the remote Agents prior to rolling back the Coordinator machine.

To perform a quick rollback:

1. Open the Coordinator Monitor on the Primary Coordinator machine.
2. In the File menu, select Version Rollback... -> Remote Agent(s)...
   ”。
   这将打开版本回滚窗口。在下拉列表中，选择“Quick
    .
   The Version Rollback window opens.
3. In the drop-down list, select Quick Rollback (Recommended)
   ”，然后单击“OK”。
   这将打开选择 IncrediBuild 安装程序窗口。
4. 选择要回滚到的版本的安装程序可执行文件（例如 ibsetup822.exe），然后单击“OK”。
   远程Agents应启动回滚进程。
   每个远程Agents计算机上都会显示一个回滚确认窗口。
5. 如果需要，请访问每个远程Agents，然后单击“OK”以批准回滚进程。
   注意：在远程Agents完成版本回滚后，它们将出现在Coordinator监视器中并显示“不兼容版本”状态。
6. 在完成远程Agents版本回滚后，在“File”菜单中选择“Version
   , and then click OK.
   The Select an IncrediBuild Setup program window opens.
7. Choose the Installer executable for the version you wish to rollback to (e.g. ibsetup822.exe) and then click OK.
   The Remote Agents should start the rollback process.
   A Rollback confirmation window appears on each of the Remote Agent computers.
8. If required, access each of the remote Agents and click OK to approve the rollback process.
   Note: Once the remote Agents have completed the version rollback, they appear in the Coordinator Monitor with "Incompatible Version" status.
9. After completing the remote Agents version rollback, in the File menu, select Version Rollback... -> Local Coordinator... .
   ”。
   
   
   这将打开 IncrediBuild Coordinator弹出窗口。
10. 单击“OK”以确认Coordinator计算机回滚。
11. 单击“Next”，然后单击“Finish”以便在Coordinator计算机上完成回滚进程。

方法 2 - 完全回滚

使用此方法，您将在Coordinator和所有Agent计算机上完全卸载当前版本，然后安装旧版本。 回滚进程从Coordinator监视器执行。

要执行完全回滚：

1. 在primary Coordinator计算机上打开Coordinator监视器。
2. 在“File”菜单中，选择“Version Rollback...”
3. 浏览文件系统并选择旧 IncrediBuild 版本的安装应用程序文件。 完成后单击“OK”。
4. Coordinator监视器现在应该向当前连接到Coordinator的所有Agents发送版本回滚请求。 这会导致在运行 IncrediBuild Agents的所有计算机上执行以下步骤（请注意，所有步骤都需要用户交互）：
   1. 当前版本的卸载进程。
   2. 旧版本的安装进程。
5. 回滚进程现在会询问您是否要在运行Coordinator的计算机上执行版本回滚。 您可能会希望稍后执行此操作，以进行另一个版本的回滚操作（如果某些Agents拒绝版本回滚请求或某些Agents当时未连接到Coordinator，这项功能非常有用）。 要运行另一个版本的回滚进程，请重复上述过程。
6. 选择在运行Coordinator的计算机上运行版本回滚进程后，请按照下列步骤操作：
   
   1. 完成当前版本的卸载进程。
   2. 完成旧版本的安装进程。 在组件选择页面中，选择“IncrediBuild Coordinator”。
   3. 双击许可证文件以激活许可证。

注意:

1. The IncrediBuild Coordinator pop-up window opens.
2. Click OK to confirm the Coordinator Machine rollback.
3. Click Next and then Finish to complete the rollback process on the Coordinator machine.

Method 2 – Full Rollback

With this method, the current version is fully uninstalled on the Coordinator and all Agent machines, and the older version is installed instead. The Rollback process is performed from the Coordinator Monitor.

To perform a full rollback:

1. Open the Coordinator Monitor on the Primary Coordinator machine.
2. In the File menu, select Version Rollback...
3. Browse the file system and select the older IncrediBuild version's Setup application file. Click OKwhen done.
4. The Coordinator Monitor should now send version rollback requests to all Agents currently connected to the Coordinator. This causes the following steps to be executed on all the computers running IncrediBuild Agents (note that all steps require user interaction):
   1. An Uninstall process of the current version.
   2. A Setup process of the older version.
5. The Rollback process now asks if you would like to perform a version rollback on the computer running the Coordinator. You may prefer to do this at a later time, in order to perform another version rollback operation (useful if some of the Agents declined the version rollback request or some Agents were not connected to the Coordinator at the time). To run another version rollback process, repeat the above process.
6. Once you've selected to run a version rollback process on the computer running the Coordinator, follow these steps:
   

   1. Go through the current version's Uninstall process.
   2. Go through the older version's Setup process. In the Component Selection page, select IncrediBuild Coordinator.
   3. Double-click your license file to activate your license.

Notes:

• After the version rollback process has been run on the computer running the Coordinator, Agents that have not performed the version rollback process may do so by going through either of the following processes:
  • Method 1 (Quick Rollback): Right-click the Agent tray-icon and select Update Version.
  • Method 2 (Full Rollback):
    1. Uninstall IncrediBuild.
    2. Run the older version's Setup application.
