Open the EPLAN License Manager or the Rehost Tool on the current machine. Select the license you wish to move. Click on the "Return" or "Rehost" button.

OS Updates: Migrating to the latest Windows versions that require a fresh EPLAN installation.

"License is already in use"This happens if the return process in Step 1 failed or was skipped. You cannot activate a license that hasn't been officially returned. If the old machine is broken and cannot be accessed, you must contact EPLAN support to have the license manually released.

Regular Backups: Always backup your EPLAN parts database and templates before a rehost or version upgrade.
