Hi, Thanks to Eric I've seem to found the history of tag and branches issue. [1]
"Obviously, SVN is not Git. During the process of cloning a Git repository from the SVN repository, commits for tags and branches can get a bit confused. Each project is responsible for providing a list of ref updates that they would like to have applied to their repository before accepting it as writable." So does one of the committers who voted for Git want to prepare this (I'm not even sure what they are asking for here): Updates should be specified in a three column format of: oldsha newsha ref-name I'm mostly out of action for the next 2 days (at a conference which I'm speaking at) and over the weekend. Thanks, Justin 1.https://git-wip-us.apache.org/docs/switching-to-git.html
