Migrating information betwixt Git repositories, piece preserving their invaluable past, is a communal situation for builders. Merely copying and pasting received’t chopped it โ you’ll suffer the important discourse of commits, authorship, and the development of your codification. This blanket usher dives into the about effectual strategies for transferring records-data from 1 Git repository to different (with out cloning), guaranteeing your task’s past stays intact. We’ll research strategies similar git filter-subdivision and git subtree, evaluating their strengths and weaknesses, and demonstrating however to instrumentality them efficaciously.
Utilizing git filter-subdivision for Selective Record Migration
The git filter-subdivision bid is a almighty implement for rewriting Git past. Piece it provides large flexibility, it ought to beryllium utilized with warning, particularly successful collaborative environments, arsenic it completely alters the perpetrate past. This technique is champion suited for extracting circumstantial information oregon directories from a ample repository into a fresh 1.
For illustration, ideate you person a monolithic repository and privation to isolate a circumstantial module into its ain task. git filter-subdivision permits you to make a fresh repository containing lone the past associated to that module, efficaciously carving retired a same-contained task with its afloat past.
A statement of warning: Erstwhile you rewrite past with git filter-subdivision, you’ll demand to unit-propulsion the modifications to the distant repository. Guarantee everybody connected your squad is alert of this alteration to debar conflicts.
Leveraging git subtree for Sustaining Task Discourse
The git subtree bid offers a much surgical attack to migrating records-data. It permits you to merge the past of a subdirectory from 1 repository into different, preserving the first perpetrate construction. This is perfect once you privation to combine a constituent into a fresh task piece retaining its humanities discourse.

See the script wherever you privation to incorporated an unfastened-origin room into your task. git subtree permits you to embed the room’s codification and its absolute past straight into your repository, making it casual to path adjustments and negociate updates.
Measure-by-Measure Usher to Utilizing git subtree
- Adhd the distant repository containing the records-data you privation to decision:
git distant adhd -f another-repo <another-repo-url> - Merge the subdirectory into your actual repository:
git subtree adhd --prefix=<way/to/subdir> another-repo maestro - Propulsion the modifications to your distant repository:
git propulsion root maestro
Selecting the Correct Technique for Your Wants
Selecting betwixt git filter-subdivision and git subtree relies upon connected your circumstantial occupation. filter-subdivision provides much granular power complete past rewriting however requires cautious information owed to its imperishable quality. subtree offers a safer, much built-in attack for merging subdirectories with their past.
Presentโs a speedy examination:
- git filter-subdivision: Perfect for extracting circumstantial records-data/directories and rewriting past. Usage cautiously successful shared repositories.
- git subtree: Champion for merging subdirectories with past intact. Safer for collaborative initiatives.
Knowing the nuances of all bid volition empower you to brand the correct prime for your task’s wants.

Question & Answer :
Our Git repositories began retired arsenic elements of a azygous monster SVN repository wherever the idiosyncratic initiatives all had their ain actor similar truthful:
project1/branches /tags /trunk project2/branches /tags /trunk
Evidently, it was beautiful casual to decision information from 1 to different with svn mv. However successful Git, all task is successful its ain repository, and present I was requested to decision a subdirectory from project2 to project1. I did thing similar this:
$ git clone project2 $ cd project2 $ git filter-subdivision --subdirectory-filter profoundly/buried/java/origin/listing/A -- --each $ git distant rm root # truthful I don't unintentionally overwrite the repo ;-) $ mkdir -p profoundly/buried/antithetic/java/origin/listing/B $ for f successful *.java; bash > git mv $f profoundly/buried/antithetic/java/origin/listing/B > finished $ git perpetrate -m "moved records-data to fresh subdirectory" $ cd .. $ $ git clone project1 $ cd project1 $ git distant adhd p2 ../project2 $ git fetch p2 $ git subdivision p2 remotes/p2/maestro $ git merge p2 # --let-unrelated-histories for git 2.9+ $ git distant rm p2 $ git propulsion
However that appears beautiful convoluted. Is location a amended manner to bash this kind of happening successful broad? Oregon person I adopted the correct attack?
Line that this includes merging the past into an present repository, instead than merely creating a fresh standalone repository from portion of different 1 (arsenic successful an earlier motion).
If your past is sane, you tin return the commits retired arsenic a spot and use them successful the fresh repository:
cd repository git log \ --beautiful=e mail \ --spot-with-stat \ --reverse \ --afloat-scale \ --binary \ -m \ --archetypal-genitor \ -- way/to/file_or_folder \ > spot cd ../another_repository git americium --committer-day-is-writer-day < ../repository/spot
Oregon successful 1 formation
git log --beautiful=e mail --spot-with-stat --reverse --afloat-scale --binary -m --archetypal-genitor -- way/to/file_or_folder | (cd /way/to/new_repository && git americium --committer-day-is-writer-day)
Trace: If commits successful the origin taskโs subdirectory ought to beryllium extracted to a fresh repository base listing, git americium tin beryllium fixed an statement similar -p2 to distance other directories from the spot.
