Hi Gavin. The Dev server is a separate server for testing out features before they are released to the roll20 community as a whole on the Production/Main server. You receive all the perks of a Mentor regardless if you decide to move or create a new campaign to the Dev server. Some versions of API scripts(Mentor level feature) may only work on the Dev. You can copy an existing campaign to the Dev by logging onto the Dev server, go to the Home page and use the "Copy from Production" . NOTE(taken from another thread Copying a prod campaign to the dev server. What's the point? ): The Aaron said: It copies all of the contents of the campaign, but does not currently copy the externally configured details you mentioned above. So, it DOES copy all of the pages, characters, handouts, music, tables, decks and macros. It does not copy the API scripts (sad panda), character sheet, background image, forum posts, etc. So, after copying to the Dev you'll have to attach a character sheet template, any scripts used, and setup any of the external type features you want/need. You will have a new game join link as well that you will need to send to your players. Hope this helps. Cheers
