Clearcase：从Git迁移到ClearCase [英] Clearcase : Migrate from Git to ClearCase

问题描述

因为我们需要将我们的回购转换为CC并保留历史记录。

$ b $对于这种迁移没有真正的经验，但如果你需要保留历史，你可以轻松地为一个分支（比如master ），对于多个分支来说更难：

  git filter-branch --tree-filter'clearfsimport -preview -rec  - nset。 m：\MyView\MyVob\ParentDirectory'HEAD 
  

对于git仓库的每次提交，你做一个clearfsimport，为了添加或更新ClearCase动态视图中的文件（如在ClearCase中创建一个新的子目录结构？ ）

详细了解 filter-branch --tree 在重写git历史记录替换每个文件中的单词，通常用于重写历史记录，但在此用于其他目的（ clearfsimport ）。

Could you please share your experience with Git to Clearcase migration ?

As we need to convert our repo to CC and keep history.

解决方案

There is no real "experience" of such a migration, but if you need to keep the history, you can do so easily for one branch (like master), it is more difficult for multiple branches:

git filter-branch --tree-filter 'clearfsimport -preview -rec -nset . m:\MyView\MyVob\ParentDirectory' HEAD

For each commit of the git repo, you do a clearfsimport, in order to add or update files in a ClearCase dynamic view (as explained in "Creating a new subdirectory structure in ClearCase?")

See more about the filter-branch --tree filter in "Rewrite git history replacing a word in every single file", used usually to rewrite history, but used here to for another purpose (clearfsimport).
