nc -nvlp 1337

Then run the following workflow in GH actions:

Rewriting repository history

Sometimes history rewrites are required in order to migrate repositories into github.com. Several factors can dictate the need to rewrite history of a repository:

  • objects larger than 100Mb
  • commits larger than the 2GB push limit

Although rewriting history might not be required for your repository to migrate to github.com, you may consider rewriting history for several reasons:

  • migrate large objects to LFS
  • cleanup previous mistakes or bad practices that caused repo bloat
  • remove secrets from repo history

ghec-importer examples

The following example will remove the teams from the migration_archive.tar.gz file.

export GHEC_IMPORTER_ADMIN_TOKEN="xxxx"
ghec-importer prepare-archive -r teams migration_archive.tar.gz

The following example will import the migration_archive.tar.gz into the robandpdx-migaration5 org and enable actions on the repo. If there is a repo name conflict, if will be resolved by adding the source org name to the repo name as a prefix.
