I want to migrate Server to DataCenter.
"Apps extend what your team can do with Atlassian applications, so it's important to make sure that your team can still use their apps after migrating to Data Center. When you switch to Data Center, you'll be required to switch to the Data Center compatible version of your apps, if one is available. "
What I understand is, that I have to install the datacenter version app from atlassian marketplace and install every plugin again. Is that right?
And what about the licence of the apps? Do I have to buy new ones?
upgrading to Data Center usually goes without any migration effort. It is rather an exchange of license keys. As soon as you put in the DC license you have a single node system ready to use.
And yes you are right, each app that has a DC version available in the marketplace also needs to be upgraded.
Apps that are only available for Server will usually work fine within a DC environment.
