IPOPs v1.1.6 — One-Click License Migration for Houdini 21

We’re excited to announce IPOPs for Houdini 21 (v1.1.6), bringing a smoother licensing experience with a brand-new License Migrator.

Why This Matters

Moving to a new Houdini version often means resetting your user preference folder — and manually relocating license files can be tedious. With this update, you can carry forward all your IPOPs licenses from older Houdini installs into Houdini 21 with a single click.

Zero internet dependency: The tool works offline by copying your encrypted *.license / .lic files.

Instant migration: Your validation flow remains unchanged, so there’s no need to re-activate.

Cross-platform ready: Windows & Linux Houdini 21 package JSONs are now included.

What’s New in v1.1.6
Added

ipops_licensing/scripts/ipops_license_migrator_client.py

ipops_licensing/packages-json/IPOPs_linux_h21.json

ipops_licensing/packages-json/IPOPs_windows_h21.json

Updated

ipops_activate_license-3.0 now includes a Migrate All IPOPs Licenses action.

How to Use (3 Simple Steps)

Select your old Houdini prefs path
In ipops_activate_license-3.0, point to your previous Houdini home folder (e.g. $HOME/houdini20.5/ or C:\Users\<you>\Documents\houdini20.5).


Click “Migrate All IPOPs Licenses”
The tool copies all valid IPOPs license files into your current $HOUDINI_USER_PREF_DIR.


Done
A summary dialog lists what was copied (and anything missing). Restart Houdini if your setup loads licenses at startup.


What Gets Migrated

All installed IPOPs product licenses (*.license files)

IPOPs_Standard_License.lic

IPOPs_StandardLicenseType.txt

The migrator never alters keys or contacts servers — it simply relocates your existing license files.

Compatibility

Houdini: 21.0

OS: Windows & Linux (H21 packages included)

Backwards-compatible: No changes to activation/validation logic.

Notes

If the old and new user preference folders are the same, migration is skipped automatically.

Missing files are reported in the summary dialog so you can double-check your source path.
