I have two drupal 7 sites and one of them has about 21 content types that does not exists in the other drupal 7 site. It's not a data merge so it's more of a data copy. I know there is the migrate module, but that seems a bit overkill for something like this as I am not merging data into an existing content type. It should just create a new content type on the new site and import all the fresh datas in.
What's the best approach or modules that should be used in this scenario?
I have never used migrate module before, so I'm assuming it's pretty complex as it can deal with many types of data. I remember there was a module which let you copy content from one site into the other.
The only complexity here is that these content types have node references and entity references associated to them. What issues might arise from that?
