迁移到独立环境或 Automation Suite 环境

注意:AI Center 2021.10 的传统升级不可用,您需要安装 AI Center 独立版 2021.10 或作为新的 Automation Suite 安装的一部分,并且可以从以前的环境迁移工作。此迁移脚本适用于 AI Center 独立版或 Automation Suite 环境这两种安装类型。

概述

使用此过程从 2021.4 或 2020.10 迁移到 2021.10。为此,需要全新安装和迁移,而不是升级。

使用以下步骤将 AI Center™ 租户数据迁移到 AI Center 独立环境或 Automation Suite 环境。此过程为以下项目提供迁移支持:

  • 数据库
  • 数据集
  • ML 包
    注意:在部署和训练迁移的 DU ML 包之前,必须执行 Document Understanding 按需捆绑包。

    如果进行离线安装,请确保将具有相同主要版本的模型添加到开箱即用的模型中。有关离线安装模型的更多信息,请参阅 ML 包离线安装

先决条件

确保 AI Center™ 在这两种环境中均已启动并正在运行。

此外,运行迁移脚本的计算机必须满足以下先决条件:

  • 安装了以下依赖项的 Linux 计算机:aws s3s3cmdjqzip。该计算机可以是其中一台 AI Center 计算机,也可以是新计算机。有关详细信息,请参阅下面的示例。

安装 aws s3、s3cmd、jq、zip 依赖项

注意:如果存在未满足的依赖项,请在不使用包的情况下运行以下命令:
sudo susudo apt install -y jq awscli s3cmd zip gitsudo apt --fix-broken installsudo apt install -y jq awscli s3cmd zipsudo susudo apt install -y jq awscli s3cmd zip gitsudo apt --fix-broken installsudo apt install -y jq awscli s3cmd zip
  • 此处安装 MS SQL 实用程序。您可以通过运行以下命令来执行此操作:
    sudo su
    curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list | sudo tee /etc/apt/sources.list.d/msprod.listsudo apt-get update 
    sudo apt-get install mssql-tools unixodbc-devsudo apt-get update 
    sudo apt-get install mssql-toolsecho 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profileecho 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
    source ~/.bashrcsudo su
    curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list | sudo tee /etc/apt/sources.list.d/msprod.listsudo apt-get update 
    sudo apt-get install mssql-tools unixodbc-devsudo apt-get update 
    sudo apt-get install mssql-toolsecho 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profileecho 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc
    source ~/.bashrc
  • 与两个 AI Center™ 实例的连接。
  • 与两个 Orchestrator 实例的连接(以防实例不同)。
  • 与 SQL Server 的连接(以防实例不同)。
  • 可以访问两个 AI Center 实例。

程序

步骤 1:在 Automation Suite 或新 AI Center 环境中创建具有相同名称的租户

在 Automation Suite 或新 AI Center™ 环境中为要迁移的每个租户创建相应的租户。

步骤 2:在第一台计算机(也称为源计算机)上生成 Storage-creds.json 文件

此步骤需要在第一台计算机上运行,即您要迁移到新环境的计算机。

  1. 使用 SSH 连接到要迁移的计算机。
  2. 通过执行以下命令生成 storage-creds.json 文件:
    wget https://raw.githubusercontent.com/UiPath/ai-customer-scripts/stable/platform/sfmigration/storagemigration/get-credentials.sh
    chmod 777 get-credentials.sh
    ./get-credentials.shwget https://raw.githubusercontent.com/UiPath/ai-customer-scripts/stable/platform/sfmigration/storagemigration/get-credentials.sh
    chmod 777 get-credentials.sh
    ./get-credentials.sh
注意:如果从第三台计算机运行,请确保运行以下命令:
./get-credentials.sh {PUBLIC_IP_REPLICATED_MACHINE}./get-credentials.sh {PUBLIC_IP_REPLICATED_MACHINE}
注意:如果在运行上述脚本后显示以下错误消息,请运行 bash -l 命令,然后再次尝试运行上述脚本


步骤 2 中生成的文件 (storage-creds.json) 将用于后续步骤。确保在本地复制并保存文件的内容。

步骤 3:在第二台计算机上生成 Storage-creds.json 文件

此步骤需要在第二台计算机上运行,即在 Automation Suite 环境中运行的计算机。

  1. 在 Automation Suite 计算机上打开端口 22。
  2. 使用 SSH 连接到 Automation Suite 计算机。
  3. 运行以下命令:
    sudo su
    export KUBECONFIG=/etc/rancher/rke2/rke2.yaml PATH=$PATH:/var/lib/rancher/rke2/binsudo su
    export KUBECONFIG=/etc/rancher/rke2/rke2.yaml PATH=$PATH:/var/lib/rancher/rke2/bin
  4. 通过执行以下命令下载凭据文件:
    wget https://raw.githubusercontent.com/UiPath/ai-customer-scripts/stable/platform/sfmigration/storagemigration/get-credentials-sf.sh
    chmod 777 get-credentials-sf.sh
    ./get-credentials-sf.shwget https://raw.githubusercontent.com/UiPath/ai-customer-scripts/stable/platform/sfmigration/storagemigration/get-credentials-sf.sh
    chmod 777 get-credentials-sf.sh
    ./get-credentials-sf.sh
步骤 4 中生成的文件 (storage-creds-sf.json) 将用于后续步骤。确保在本地复制并保存文件的内容。

步骤 4:配置执行脚本的计算机

在完成以下步骤之前,请在 Automation Suite 环境中手动创建一个具有相同名称的租户。无论必须迁移哪个租户,都必须在 Automation Suite 中创建相应的租户。

此步骤需要在执行脚本的计算机上运行。

  1. 运行以下命令以下载迁移脚本(这将从公共 git 存储库下载脚本):
    sudo su 
    cd ~
    mkdir migration
    cd migration
    git clone https://github.com/UiPath/ai-customer-scripts
    cd ai-customer-scripts
    git checkout stable
    cd platform
    chmod 777 -R sfmigration
    cd ~/migration/ai-customer-scripts/platform/sfmigration/storagemigration/sudo su 
    cd ~
    mkdir migration
    cd migration
    git clone https://github.com/UiPath/ai-customer-scripts
    cd ai-customer-scripts
    git checkout stable
    cd platform
    chmod 777 -R sfmigration
    cd ~/migration/ai-customer-scripts/platform/sfmigration/storagemigration/
  2. SOURCE_CREDENTIAL_FILE 文件中的内容替换为 storage-creds.json 中的内容(请参阅步骤 2)。
  3. TARGET_CREDENTIAL_FILE 文件中的内容替换为 storage-creds-sf.json 中的内容(请参阅步骤 3)。
  4. 通过运行以下命令转到基本目录:
    cd ~/migration/ai-customer-scripts/platform/sfmigration/cd ~/migration/ai-customer-scripts/platform/sfmigration/
替换 input.json 文件中的详细信息(目录中已存在的文件)。为便于参考,凭据在 input.json 文件中标记为 TO-BE-REPLACED

下面提到了带有每个字段说明的示例 JSON 文件。

                }
        ]
}

可以通过以下步骤获取 SRC_TENANT_ID:

  1. 单击 AI Center™ 应用程序主页上的 UiPath 徽标。
  2. 右键单击浏览器并转到“检查”。打开“检查”窗口后,检查项目 API 调用的“网络”选项卡。租户 ID 可以在“预览”部分中看到,如下面的屏幕截图所示。


  3. 在执行脚本的计算机中添加 Automation Suite 计算机的对象存储的 DNS。这可以在创建 Automation Suite 环境的管道的扩展程序选项卡中找到。
    sudo bash -c "echo "LB_IP objectstore.DNS_NAME" >> /etc/hosts"sudo bash -c "echo "LB_IP objectstore.DNS_NAME" >> /etc/hosts"

步骤 5:运行迁移脚本

转到使用情况目录中下载 sfmigration 的文件夹:运行以下命令:
cd ~/migration/ai-customer-scripts/platform/sfmigration/
 
 ./mastermigrationscript.sh input.jsoncd ~/migration/ai-customer-scripts/platform/sfmigration/
 
 ./mastermigrationscript.sh input.json

故障排除

创建租户

在运行迁移脚本之前,需要在 Automation Suite 环境中创建租户。

重新运行迁移

迁移脚本仅用于迁移数据集和 ML 包一次。在极少数情况下,迁移完成后在来源环境中添加了一些额外的数据集或 ML 包,那么在这种情况下,需要重新运行迁移。在重新运行迁移之前,在目标数据库中运行以下命令:

delete from [ai_pkgmanager].[ml_package_versions_temp];
delete from [ai_pkgmanager].[projects] where tenant_id in ('T1','T2',...);
delete from [ai_pkgmanager].[ml_packages] where tenant_id in ('T1','T2',...);
delete from [ai_pkgmanager].[ml_package_versions] where tenant_id in ('T1','T2',...);
delete from [ai_trainer].[datasets] where tenant_id in ('T1','T2',...);delete from [ai_pkgmanager].[ml_package_versions_temp];
delete from [ai_pkgmanager].[projects] where tenant_id in ('T1','T2',...);
delete from [ai_pkgmanager].[ml_packages] where tenant_id in ('T1','T2',...);
delete from [ai_pkgmanager].[ml_package_versions] where tenant_id in ('T1','T2',...);
delete from [ai_trainer].[datasets] where tenant_id in ('T1','T2',...);
注意:上面查询中的 'T1''T2'、... 是目标环境中的租户 UUID。这些是运行迁移脚本 ./mastermigrationscript.sh input.json 时传递的 input.json 文件中提到的 DESTINATION_TENANT_ID

然后,您可以使用以下命令重新运行迁移:

cd ~/migration/ai-customer-scripts/platform/sfmigration/
 
./mastermigrationscript.sh input.jsoncd ~/migration/ai-customer-scripts/platform/sfmigration/
 
./mastermigrationscript.sh input.json

克隆的包

迁移后,来源环境中的克隆 ML 包将在 Automation Suite 环境中标记为 VALIDATION_FAILED。迁移完成后,需要在目标环境中再次克隆这些包。
注意:在这种情况下,克隆的包是指来自 UiPath开源包的包。
