I'm part of a smaller department of a large company and we currently have our own Bitbucket server license and have Bitbucket 4 installed. We're finally able to access the corporate enterprise license and plan on migrating to data center as well as eventually upgrading to Bitbucket 6. We're like to upgrade to data center first (just because of some licensing things, we want to go ahead and get a data center license from corp before our server license expires in May). Can we upgrade to Bitbucket Data Center from Bitbucket 4 server or do we need to upgrade to server 5 or 6 and then migrate to data center?
