Replacing 3.6.3 server - Using MySQL

I am going to be replacing an existing Openfire 3.6.3 server in my organization that is currently using an external (on another server) MySQL database. The server is an older version of Ubuntu and isn’t really practical to upgrade in place. I’d like to retain the current database if possible because we already have some custom software set up to query the openfire database for chat logs so that managers can monitor chats between their employees as needed. My question is, if I stand up a server using the newest version of Openfire, can I simply connect to that existing database, or has there been changes made to the database schema since 3.6.3? We are also using LDAP authentication against Active Directory if that makes a difference. Thanks!
