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 stackoverflow.com/questions/747075/… ? They don't work? or? — Tim

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

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>

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.

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.

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