How to migrate and integrate projects in GitLab

Introduction:
In the software development process, project migration and integration is an important task. As a popular code hosting platform, GitLab provides a series of convenient tools and functions to support project migration and integration. This article will introduce the specific steps for project migration and integration in GitLab, and provide some code examples to help readers better understand.

1. Project migration
Project migration is the process of migrating an existing code base from a source code management system to GitLab. The following are the specific steps:

1. Create a new project on GitLab
   First you need to create a new project on GitLab. You can create a project by clicking the "New Project" button in the upper right corner of the page, and then filling in the project name, description, and selection visibility.
2. Clone the source code library to the local
   Use the command line or graphical interface tool locally to clone the source code library to a local directory.
3. Add the remote warehouse of the GitLab project
   Enter the source code library directory you cloned to, and use the following command to add the remote warehouse of the GitLab project to the local:
   git remote add origin [project's GitLab warehouse address]
4. Push code to GitLab
   Use the following command to push local code to GitLab's remote warehouse:
   git push -u origin master

2. Project integration
Project integration is the process of merging codes from multiple warehouses into one warehouse. The following are the specific steps:

1. In GitLab Create a new project on
   You also need to create a new project on GitLab to integrate code from multiple repositories.
2. Clone the new project to the local
   Use the command line or graphical interface tool locally to clone the new project to a local directory.
3. Add other repositories as submodules of the new project
   Use the command line in the root directory of the new project or edit the .gitmodules file, and use the following command to add other repositories as submodules:
   git submodule add [Other warehouse address]
4. Initialize submodule
   Use the following command to initialize the submodule:
   git submodule init
5. Update submodule
   Use the following command to update the submodule:
   git submodule update
6. Commit changes
   Use the following command to submit the change:
   git commit -m "Add submodules"
7. Push code to GitLab
   Use the following command to push local code to GitLab's remote repository:
   git push -u origin master

3. Code Example
The following is an example that demonstrates how to migrate and integrate projects through the command line:

# 创建新项目并克隆到本地
git clone [新项目的GitLab仓库地址]
cd [新项目目录]

# 迁移源代码库到GitLab
git remote add origin [源代码库的地址]
git push -u origin master

# 创建新项目用于集成和克隆到本地
git clone [新项目的GitLab仓库地址]
cd [新项目目录]

# 添加其他仓库为子模块
git submodule add [其他仓库地址]

# 初始化子模块
git submodule init

# 更新子模块
git submodule update

# 提交变更
git commit -m "Add submodules"

# 推送代码到GitLab
git push -u origin master

Conclusion:
The above is Specific steps for project migration and integration in GitLab. Through the above steps, you can easily migrate existing code libraries to GitLab and achieve code integration of multiple warehouses. We hope that the code examples provided in this article will be helpful to readers and help them better understand the use of GitLab.
