Migrate Kolab 16 to a new system

To migrate data from one Kolab 16 installation to another follow the following steps:

• Stop all services on the old and new system.
• Copy IMAP, LDAP, and MYSQL data to the new machine
• Start all services again.

This approach is very generic and makes some assumptions:

• The new system replaces the old system (e.g. for an OS upgrade)
• Downtime is acceptable

Advanced techniques

For large deployments the above may not be sufficient, and it is possible to things such as incremental migrations or live migrations, however, this is out of scope for this article.
