I have SVN project with the below directory structure
root
|-->branches
|-->trunk
--> file 1
--> file 2
|-->release
--> file 1
--> file 2
|-->tags
|-->tag1
|-->tag2
|-->tagN
The problem with moving from SVN to GIT is I can map
SVN to GIT
branches -- branches
tags -- tags
trunk -- trunk
release -- ??????
How can I map release folder to a GIT folder
I think the should be also tags. It depends mainly in how you used them. Take a look to the Atlassian tutorial about migrating from Subversion to Git. It's quite straight and clear: https://www.atlassian.com/git/tutorials/migrating-overview. You can experiment, look what you get and if you don't like you can always start over.
