EDIT: I was using dialog in Sitecore Rocks - seems there is a better one in actual admin interface where I can set publish to/from dates for each version.. Just testing to see if this works..
So, I am looking into delayed publishing, and want to know what I can acheive out of the box, and what I might need to use a plugin for.
I have a page, that is already published, i.e. the homepage.
I want to make a change to this page (in this case, on a field on page itself, and not any dynamically bound content), at a specific Date/Time but don't want to have to publish at that specific moment.. so, I set the "Publishable from" date to my required date/time, and publish item. Issue I am having is this causes the page to become unpublished (and therefore I get an error) until the required time comes along. I want to keep V1 active until V2's publish time as come and that becomes the active version..
I've already enabled
<agent type="Sitecore.Tasks.PublishAgent" ... in the config file.
