There is no "migration" to be done really unless you're moving between servers.
JIRA Software is an application that you can add to JIRA Core. (The download for "JIRA Software" is actually JIRA Core with Software pre-installed for you). If you add the application to your existing installation of Core, all the functions become enabled, and all you need to do is license it, enable the users and start using it. Data doesn't need to move.
If you do want to move servers (i.e. migrate), you can install JIRA Software cleanly, take a backup of the old system and restore it into the new one. It's not really even a migration.
You will need to pay more. JIRA Software licenses cost more than JIRA Core ones. But, JIRA Software licenses include Core usage, so you could do something like 25 Software users and 50 Core, giving you a total of 75 users with full access to all the Core functions.
