completely move a channel from one hub to another
Mike explained that for a complete import of content during the channel move, it is necessary to transfer parts of program code from Zap project to Hubzilla project. See explanation here
Basically cut and paste working code (programming instructions) from a platform where this particular feature (nomadic identity) was further developed and refined and improved.
I suggest that such a transfer of program code from Zap to the Hubzilla project is done, so that Hubzilla users can benefit from the feature "completely move a channel from one hub to another".
