"We are moving to the Data Center Editions for Jira. Unfortunately, the Workfront Plugin is not certified for the Data Center edition which is common with the free apps since they are not usually tested for scale. We will reach out to vendor and see what they say about support options and ability for the app to scale to see if they will support it on the Data Center edition.
In any case, I have some concerns about installing this app because the reviews for the Cloud offering are terrible, and I do not want to install something that is error prone and has to be frequently reconfigured to make work. There are no reviews for the Server versions of this plugin so it’s hard to say precisely."
