Has anyone used the icewarp converter app, I have a copy that I downloaded last year, when I run the converter, it looks like it extracts the domains and creates user folder etc.  But when I edit the domainlist json file as described, smartermail tries to convert but doesnt complete when I look at the log, it doesnt give allot of information this is what I get.

When Finished I look in the admin webgui the domain now shows, but when i click on the domain, it gives and error saying in red popup message "Object reference not set to an instance of an object" and the gui page for the domain is blank not even rendered no data or fields.

Anyone have any ideas?

Is there another way to migrate a domain from icewarp without doing an import of each account through the webmail.
