Chef Migrate release notes

Chef Migrate 1.2.33

Release date: May 22, 2026

Habitat-related paths now respect the SYSTEMDRIVE environment variable (for example, D:\hab, E:\hab), allowing you to install Chef Infra Client 19 (ICE) on any drive.
Omnibus-related paths remain hardcoded to C:\opscode to maintain backward compatibility with legacy Omnibus installations.

Release date: May 20, 2026

Fixed an issue where Chef Migrate could fail and corrupt the Chef Infra Client installation if Chef Infra Client is running during migration. Chef Migrate now detects running Chef Infra Client processes and waits up to five minutes for them to complete before proceeding.
Fixed an issue where migration failed on systems running legacy Chef Infra Client versions 13 or 14. The Omnibus uninstall scripts for these versions deleted binaries from /usr/bin during package removal. Chef Migrate now automatically restores these binaries after Omnibus uninstall using hab pkg binlink.

Adds support for Linux ARM distributions.
Adds the --set-chef-schedule-task flag to create a Windows scheduled task that runs Chef Infra Client every 30 minutes.
Adds support for both new (hab/pkgs/chef/hab/) and legacy (hab/pkgs/core/hab/) Habitat package path formats, ensuring compatibility with all Chef ICE package versions.
Package removal writes a log file to a platform-specific location, including timestamps, removal status, binlink restoration events, and exit codes:
- Linux and macOS: /var/log/chef-package-removal.log
- Windows: %TEMP%\chef-package-removal.log

Release date: March 26, 2026

The chef-client -v command now correctly points to the new Habitat-based Chef Infra Client install when it’s installed with Chef Migrate and a previous Omnibus-based Chef Infra Client version is preserved with the --preserve-omnibus flag.
Fixed Chef Infra Client 19 installation failures on multi-drive (for example, C:, D:, E:) Windows servers.
Chef Migrate no longer fails when installing Chef Infra Client 19.x on a system with an existing Chef Automate installation. Previously, the install would fail and Chef Migrate would delete files related to Automate, for example /hab.

Don’t install Chef Infra Client 19.x on a system that already has Chef Automate running on it.
