Migrating Old Projects¶

The copier tool allows us to easily transform an old repository, that has not been created with the template, to one that is linked to a copier template.

This can be simply done by just copying the template onto an existing repository.

// Migrate an old repository to use the template
$ copier copy --trust "git+https://gitlab.tuwien.ac.at/cookbooks/templates/tu-cookbook-python" path/to/old/repo/

If a file from the template is not yet present in the repo copier will render and add it.

If a file already exists copier asks the user, wheter or not the file should be overwritten.
