[CPS-users] Content migration from a portal type to another portal type

Unfortunately you cannot change a document portal type even if you have 
common schemas: other issues need to be taken care of.
But having common schemas would make your migration easier: a script 
could take your document datamodel, and use it to create a new document.
The datamodel is just a mapping between field names and values.

Here is a suggestion (not tested), given "old_proxy", using your 
football_match portal type, and any "container" where you want to create 
the new proxy:

datamodel = old_proxy.getContent().getDataModel(proxy=old_proxy)
# change what's needed on the datamodel
datamodel.set('Date', datamodel.get('Date_and_time'))
datamodel.set('Location', datamodel.get('Place'))
# create a new document
new_proxy = container.invokeFactory('match', old_proxy.getId(), 
datamodel=datamodel)

If you'd like to do that for every document, you can query the catalog 
and search on your portal type.
