Starting from the SSH Tectia Client/Server release 5.0, the configuration file format used by SSH Tectia Client and Server has been changed to a more flexible and robust XML format. The old configurations from 4.x versions cannot be automatically transferred to 6.x, but the configuration settings need to be recreated for 6.x and distributed through SSH Tectia Manager.

A separate document, SSH Tectia Client/Server Migration Guide, gives detailed instructions on upgrading SSH Tectia Client/Server from 4.x to 6.x.
