The ISPConfig Migration Toolkit consists of two applications. The ISPConfig Migration Tool and ISPCopy. The Migration Tool helps you to import data from other control panels (currently ISPConfig 2 and 3 – 3.1, Plesk 10 – 12.5, Plesk Onyx and Confixx 3) into a new ISPConfig 3 or ISPConfig 3.1 single- or multiserver installation. The tool can also be used to import the configuration and data from an ISPConfig 3 server into another ISPConfig 3 or ISPConfig 3.1 server, use cases are e.g. merging of several standalone servers into a new single or multiserver setup and also migrations where you want to move a complete ISPConfig installation from an old to a new server.
The license is valid for one year, the number of migrations that you do with the tool is not limited.
