迁移到独立环境或 Automation Suite 环境
若要从 AI Center 2021.10 升级到更高版本,请按照“升级 AI Center”页面中的过程操作。
使用此过程从 2021.4 或 2020.10 迁移到 2022.4。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。
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 s3
、s3cmd
、jq
、zip
。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
sudo susudo apt install -y jq awscli s3cmd zip gitsudo apt --fix-broken installsudo apt install -y jq awscli s3cmd zip
sudo susudo apt install -y jq awscli s3cmd zip gitsudo apt --fix-broken installsudo apt install -y jq awscli s3cmd zip
- 从此处安装 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 ~/.bashrc
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 ~/.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。
在 Automation Suite 或新的 AI Center 环境中为要迁移的每个租户创建相应的租户。
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。
- 使用 SSH 连接到要迁移的计算机。
- 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.sh
wget https://raw.githubusercontent.com/UiPath/ai-customer-scripts/stable/platform/sfmigration/storagemigration/get-credentials.sh chmod 777 get-credentials.sh ./get-credentials.sh
./get-credentials.sh {PUBLIC_IP_REPLICATED_MACHINE}
./get-credentials.sh {PUBLIC_IP_REPLICATED_MACHINE}
bash -l
命令,然后再次尝试运行上述脚本
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。
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。
- 在 Automation Suite 计算机上打开端口 22。
- 使用 SSH 连接到 Automation Suite 计算机。
- 运行以下命令:
sudo su export KUBECONFIG=/etc/rancher/rke2/rke2.yaml PATH=$PATH:/var/lib/rancher/rke2/bin
sudo su export KUBECONFIG=/etc/rancher/rke2/rke2.yaml PATH=$PATH:/var/lib/rancher/rke2/bin - 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.sh
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.sh
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。
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。
- 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/ - 将
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)。 - 将
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)。 - 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/
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
。

可以通过以下步骤获取 SRC_TENANT_ID:
- 单击 AI Center 应用程序主页上的 UiPath 徽标。
- 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。
- 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"
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',...);
'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.json
cd ~/migration/ai-customer-scripts/platform/sfmigration/
./mastermigrationscript.sh input.json
