When you need to replace your computer or when your usage environment changes, you can follow these steps to completely transfer your organized Eagle library to a new device for continued use.

Preparation on the Old Device

Library Backup: First, ensure you perform a complete backup of the library folder on your old computer. It's recommended to compress the library folder into zip format to ensure all files and structure remain intact. Please use copy and paste operations to prevent issues during data transfer. For detailed instructions, please refer to: How to backup content saved by Eagle?
Backup Library Transfer: You can transfer the backed-up library files to your new computer using either of these two methods:
- External Hard Drive: Copy the compressed library to an external storage device (such as an external hard drive), then connect it to your new computer. Please note compatibility issues between the hard drive and system: Library on external hard drive cannot be used simultaneously on macOS / Windows systems
- Cloud Storage Services: Use cloud storage services like Dropbox, Google Drive, etc., to upload the library and download it on your new computer.

Restoring Usage on the New Device

Installation and Activation: Visit the official website to download the Eagle installation package version compatible with your new device, and complete software activation using your purchased Eagle serial number.
Import Library: Connect/download the prepared library backup files to your new computer. If you compressed the library into zip format for backup, please extract it first.
Load Library: After opening Eagle on your new computer, select "Library" > "Switch Library" from the software menu to load the library folder you migrated.
Important Notes: Ensure both computers use the same version of Eagle software to avoid compatibility issues. Be sure to verify on the new device that the migrated library content can be used completely and normally.

Environment Reset on the Old Device

Delete Library: Completely delete the library folder on your old computer to ensure file content security.
Reset Eagle Usage Records: Clear Eagle's cache and usage records on the old device to protect your product account security and provide a clean environment for the next user of that computer. For specific operation steps, please refer to this article.
Clear Software Log Files: If the old device is a macOS system, you also need to clear software log files in the system environment. For specific operation steps, please refer to this article.

After completing the above steps, you will be able to seamlessly and securely continue using Eagle software and library content on your new device.
