mise-migrate-from-pyenv

Migrating from pyenv to mise translates local and global Python version pins into a mise.toml file, updates shell integration, and safely removes pyenv artifacts while verifying interpreter consistency across projects.

The pyenv to mise migration process inventories .python-version files and pyenv-virtualenv markers, then generates a mise.toml configuration to pin Python versions while enabling idiomatic reading of those existing version files across projects.

Yes, the pyenv to mise migration supports per-project migrations by applying localized mise.toml configurations and verifying shell shims resolve correctly, ensuring your global Python environment and other projects remain intact.

During a Python environment migration from pyenv to mise, the process inventories pyenv-virtualenv markers to map existing virtual environments to the new mise configuration, ensuring shell configurations resolve to the migrated environment with fallbacks if needed.

The best way to clean up pyenv components after switching to mise is to follow an enforced migration plan that safely uninstalls pyenv artifacts only after verifying that shell configurations and Python shims resolve correctly to the new mise environment.

No, the pyenv to mise migration workflow automatically verifies interpreter consistency by checking that shell configurations and Python shims resolve to the migrated environment, applying fallbacks if needed to ensure a clean transition.
