How to upgrade / migrate 6.40 track to 7.0?

Hello all!

We are currently using the old 6.40 version of NWDI and are in the process of upgrading our portal to 7.0. We have installed a new NWDI 7.0 for this purpose.

How do I copy or migrate the contents from our old development track to the new server?

This will be done once now to test if everything works and once again in a month or so to get the latest changes.

I've read somewhere that its possible to synchronize(?) the servers but I can't find that document again.

Anyone knows how to to this or can point me to a document?

Kind regards,

Richard Linnander
