Document-Migration to the new UI? (Meeting 8)

Hi all,

in Meeting 8 Marting was presenting some new proposals about the document handling in the new UI. One point is very interesting for me: It was stated, the current documents will be working in the old UI and maybe will only readable in the new UI. If i want to work with such a document with the new UI i have to migrate it. Does this mean that this document is unusable in the old UI from this time?

And what about documents which are branched into many othe documents? If i migrate one of these branched documents and some of the other will stay unmigrated, how will this work? With all the traces and stuff? And how can i merge some content created in a branch at the old client into a document, which is already migrated?

Thanks, Jens
