[I've searched on here and googled, but can't find anything that actually makes any sense to me! - I'm a n00b to SP...our SP Dev left at very short notice...i.e. he was here yesterday, gone today...literally!]
We started with a clean SP2010 installation on Dev and Live. IN Dev we've got a single Web App, 2 site collections and each of those has a number of sub-sites, custom lists etc. etc.
1) How can I promote that from Dev to Live? I have read up on WSP files, but how do I create one for basically eveything? Or how do I create one for each collection and import it to the Live Web App?
2) What tools do I use to create and deploy the WSP Files? Does a WSP file also contain any changes to databases...e.g. when a new list is created, or do I need to create DB scripts as well?
3) In the future, if I modify a sing sub-site...how would I move that up to Live, what tools etc. etc.?
I know this has been asked before in various guises, but I can't find something that says "You need to use x tool and do this with it for this situation" I don't even know if I have all the tools I need!
