Your old schema will need minor adjustments as the classes for a lot of core types have changed.
Your old configs will also just mostly need mechanical translation from one xml to another, but probably nothing major if you were using the standard /select and friends. The biggest issue for most people upgrading is that you will need to re-index all of your data. If you were doing custom stuff for core loading/replication that can also be a big hurdle for people but solrcloud is so *easy* once you get it going that I think it pays off.
