We have just completed the first full trial migration of all ~35000 open and closed Trac tickets (as of late December) into a temporary GitHub Enterprise Server instance.
Please take a look at: https://34.105.185.241/sagemath/sage-all-2023-01-12-003/issues (accepting the self-signed server certificate) The README of https://github.com/sagemath/trac-to-github explains some of the principles of the migration. It takes about 12 hours to get all data from Trac and to write a migration archive, and then about 20 hours to import it into our server. In the final migration (planned for Feb 1), our contact at GitHub.com will import a freshly generated migration archive into GitHub.com, and we will take down our temporary GitHub Enterprise Server instance. Questions regarding the migration are very welcome. Please report any errors or wishlist items regarding the conversion here or at https://github.com/sagemath/trac-to-github/issues -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
