Migration from GIT =============== This method can be used when your repository only has one master branch. 1. Add a [[ https://c4science.ch/settings/panel/ssh/ | public ssh key ]] to your account (or a [[ https://c4science.ch/settings/panel/vcspassword/ | VCS password ]]) 2. [[ https://c4science.ch/w/c4science/repo/ | Create repo in c4science ]] 3. Clone repo from other GIT (if you don't already have a local copy) and enter repo ``` git clone https://rezzonic@git.epfl.ch/repo/scitas-benchmarks.git cd scitas-benchmarks ``` 4. Switch the remote origin ``` git remote rename origin old-origin git remote add origin ssh://git@c4science.ch:2222/diffusion/77/scitas-benchmarks.git git remote rm old-origin ``` 5. Push everything to c4science and set upstream to origin ``` git push --all --set-upstream origin git push --tag ``` 6. Wait until all the commits are parsed by phabricator to be available on the web interface (rate of import = 1000 commits/hour) Migration from SVN =============== * You can either migrate from SVN to GIT (preferred), or SVN to SVN ## SVN to GIT TODO using https://github.com/nirvdrum/svn2git ## SVN to SVN TODO

This is the manual migration procedure, there's also a script to automate the migration, see [[c4science/migration-script]] = Migration from GIT = 1. Add a [[ https://c4science.ch/settings/panel/ssh/ | public ssh key ]] to your account (or a [[ https://c4science.ch/settings/panel/vcspassword/ | VCS password ]]) 2. [[ c4science/simplerepo/ | Create repo in c4science ]] 3. Clone a fresh copy of the repository and enter the directory (even if you already have a local copy, this ensure all the remote branches are fetched) ``` cd /tmp # or any directory of your choice git clone --mirror https://rezzonic@git.epfl.ch/repo/scitas-benchmarks.git cd scitas-benchmarks.git ``` 4. Push everything to c4science, replace <URI> with the new c4science URI, for example `ssh://git@c4science.ch/diffusion/PHTEST/test.git` ``` git push --all <URI> git push --tags <URI> ``` 5.
