How to move many repos to a new github organization

Question

I have an organization with many repos (300 +) and I expect this number to grow. Therefore, from time to time, I want to clean up my organization but I would like to avoid deleting the repositories.

So right now my idea of cleaning up would be, to transfer repos that are depricated to a different organization, where I can still keep them and transfer them back, if needed, but the number of repos in the original organization goes down to ~50 or so.

I am aware of the possibility to transfer ownership within github, however repeating the process 250 times seems like a nightmare to me and I would like to automate this (there is no API endpoint to do so afaik).

Does anyone have an idea how to solve this or ever encountered a similar task?

Thanks for your help!

(In terms of automation any solution that includes python or nodejs would be preferred over other languages)

Answer 1

This github-api-bulk-transfer seems to solve exactly that problem. It also notes that: An UNSUPPORTED AND UNSTABLE PREVIEW feature for repository transfer has recently been introduced to the GitHub API that allows this process to be automated so I would proceed with caution.
