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 :

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

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

Using svnsync
USing git svn clone

Whats wrong with the anders in http://stackoverflow.com/questions/747075/how-to-git-svn-clone-the-last-n-revisions-from-a-subversion-repository ? They don't work? or? — Tim, Mar 20 '15 at 07:42
I wish to migrate to the existing Git repository and i should bring History for me. — SabareeshSS, Mar 20 '15 at 07:45
That part was pretty clear, but why dont the linked questions help you? especially the 2nd — Tim, Mar 20 '15 at 07:46
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. — SabareeshSS, Mar 20 '15 at 09:32
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. — John Szakmeister, Mar 23 '15 at 09:35

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. – SabareeshSS Mar 23 '15 at 07:31
Saby, it WILL bring HISTORY :) – Mykola Gurov Mar 23 '15 at 08:56
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. – SabareeshSS Mar 23 '15 at 13:42
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](https://www.kernel.org/pub/software/scm/git/docs/git-svn.html). – Mykola Gurov Mar 23 '15 at 14:04
Yeah I understood. But now I am talking about the first step which you had mentioned about git svn clone. – SabareeshSS Mar 23 '15 at 14:16
Yes I did git svn fetch, how can I push it now to the Git repository. – SabareeshSS Mar 24 '15 at 14:56
after successful `git svn fetch` you should get svn revisions fetched to your git-svn repository. – Mykola Gurov Mar 24 '15 at 15:02
Thanks Mykola, Its working fine. But I am unable to push it to server. – SabareeshSS Mar 27 '15 at 06:32
You may describe your next problem in a new question – Mykola Gurov Apr 09 '15 at 19:04
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 – Shenali Silva Dec 13 '19 at 07:27
