Contacts Migration Script
When migrating a whole mail server to IceWarp Server, you can use existing migration tools specific to each mail server. There are available tools for migration from Kerio, MDaemon, MMicrosoft Excel, Axigen GroupWare 602 and LANSuite.
Where there is not a specific migration tool available, it is possible to use a very handy script for migration of contacts in the vCard format.
Example of this script can be found in <install_dir>/api/php/importcontacts.php. This script imports contacts for one single user, but it uses all files from a specified folder (so there can be either always one vCard in one file, or all vCards in one file, or even a mixture). Feel free to modify the script to your needs.
