Migrating Endpoint Central refers to moving the existing installation from one computer or within the same computer but to a different location, without losing the data and the configurations made. There may be many situations where you would need to migrate, like:
You have been evaluating the product on a test computer and have decided to purchase the product. Hence, you would like to move to a dedicated computer or server.
The disk space is running low and you wish to move to a different computer.
You are upgrading the hardware.
Refer the migration document for detailed steps on migrating an Endpoint Central server installation from one computer to another without losing any data.
