During this webinar, we will explain how to get started transitioning from SVN to Git, including: - Major differences between Git and SVN - Some resources for learning more about Git - Options for migrating code from SVN to Git - A demo of what the process looks like Vertical

Some major differences between SVN and Git
– Git is distributed; SVN is centralized
– Git tracks content; SVN tracks files
– Git commits use hashes; SVN uses revision numbers
– Git operations are faster with potentially smaller repository
sizes
– Git does not impose a specific workflow
– Git allows commit staging, stashing, and rewriting history

– Merge: svn merge <target>
– Commit history: svn log <target>
Differences of some simple commands (SVN)

SVN to Git migration options
Without History
– Must flatten all work to
trunk
– Loses commit history
– Quick/easy migration
– No extra tools needed
– Acquia Support can
provide basic assistance
With History
– Retains branches/tags
– Retains commit history
– More involved migration
– Acquia Support cannot
assist with this
