Example

Case 1

• VSS repository: C:\vssrepo\library
• VSS project: $/
• VSS user: hanaguro
• Target VCS: git

Command:

> ruby vss2git.rb -r1 -s C:\vssrepo\library -u hanaguro -c git $/ >mig.log

Case 2

• VSS repository: \\vssrepo\library
• VSS project: $/PRODUCT-1
• VSS user: hanaguro
• VSS password: abc123
• Target VCS: git
• Email domain: mail.abcdefg.co.jp
• User list file: C:\doc\user.json
• Branching model: type 2
• Working root: PRODUCT-1

Command:

> ruby vss2git.rb -r1 -s \\\vssrepo\library -u hanaguro -p abc123
  -c git -d mail.abcdefg.co.jp -l c:\doc\user.json -b2 
  -w PRODUCT-1 $/PRODUCT-1 >mig.log

Let's try!

Let's migrate from sample VSS repository to Git repository.

1. Create sample VSS

Enter "sample" folder and execute "mk_sample_vss.rb".
The "mk_sample_vss.rb" do following.

• Create working folder "sample\work".
• Create Sample VSS repository in "sample\vss".

Command:

\> cd sample  
sample\> ruby mk_sample_vss.rb
Enter VSS command directory: C:\Program Files (x86)\Microsoft Visual SourceSafe

2. Excute vss2git.rb to migrate

Enter "sample" folder and execute "migrate.bat" to migrate.
The "migrate.bat" do following.

• Create git working folder "sample\git".
• Migrate VSS to git.

Command:

sample\> migrate

Change log

Ver 1.10

• Change the specification of command line option "-r".
  When you specify "-r0", you can analyze VSS to get VSS information and user list without migration.
