If you have previously worked with Parallels Plesk Sitebuilder for Linux/Unix version 2.x, and wish to upgrade to version 3.x or later, it is necessary to migrate all your data to the newer version of Plesk Sitebuilder.
Currently, it is possible to upgrade to 4.2 from the following Plesk Sitebuilder 2.x versions:
The data migration process consists of two steps:
