Incremental Migration from SVN to Git

Question

Consider my below scenario :

Suppose my svn repository contains 100 revisions, which has been migrated to Git Repository (So my Git contains the 100 revisions).

Now my svn repository got updated, say with 5 more revisions hence it has 105 revisions. How do i migrate only the revisions 101 t0 105 to my GIT repository?

The main challenges I have :

1. I dont want to sync both SVN and Git.(SVN will be decommisioned soon)
2. I need to migrate the Revisions with its history.

I tried following up with these links which dont help me,(fyi)

1. Using svnsync

2. USing git svn clone

Whats wrong with the anders in #747575 ? They don't work? or? – Leeuwarden

I wish to migrate to the existing Git repository and i should bring History for me. – Blackandwhite

That part was pretty clear, but why dont the linked questions help you? especially the 2nd – Leeuwarden

It is not bringing revisions from 101 to 105, as i mentioned I need only the latest revisions to get it updated to the migrated Git repository. – Blackandwhite

You can specify the revisiions you want to clone – Leeuwarden

I had specified the revision number. – Blackandwhite

That may be because 101 to 105 occurred somewhere other than trunk. You need to make sure you tell git-svn how you wanted Subversion mapped into Git. There's a --stdlayout option, but if that doesn't work for you, then you should specify it manually. Not all commits will appears as history for the master branch--some commits may have just been for tags, or for other branches. Those commits will appear in their respective places within the Git repo when you have them mapped correctly. – Servomotor

Answer 1

Use git-svn. When you do initial clone git svn clone ... you will get the first 100 revisions. Later you do git svn fetch which would fetch the newly appeared 5 revisions.

All 105 revisions will be present in a correct order thus the history will be preserved.

Update:

If you wish to avoid getting first 100 revisions, do git svn init with fetch initially:

git svn init ...
git svn fetch -r <svn revision you want to start from>

Mykola it wont bring HISTORY. – Blackandwhite

Saby, it WILL bring HISTORY :) – Revealment

How you are saying by doing git svn clone it ll bring only the first 100 revisions? @Mykola When I did git svn clone brought 105 revisions. – Blackandwhite

Saby, if you want to skip the earlier revisions and keep only the last 5 revisions, you may use -r/--revision option together with the initial git svn fetch. – Revealment

Yeah I understood. But now I am talking about the first step which you had mentioned about git svn clone. – Blackandwhite

Yes I did git svn fetch, how can I push it now to the Git repository. – Blackandwhite

after successful git svn fetch you should get svn revisions fetched to your git-svn repository. – Revealment

Thanks Mykola, Its working fine. But I am unable to push it to server. – Blackandwhite

You may describe your next problem in a new question – Revealment

Hi All, I have exactly the same problem. But when I do git svn fetch only the remote ref is getting updated not the local branch I have created for each ref – Granger
