Migrate and upgrade OwnCloud 9.0.11 to OwnCloud 10

Looking for help with migrating and upgrading OwnCloud. We have a system running CentOS 6 and OwnCloud 9.0.11. We have built another system with CentOS 7 and installed OwnCloud 10.0.10. What is the process to migrate to the new server and upgrade to OwnCloud 10? Can they both be done at the same time?

Thanks in advance.
