Yes, you can use Ceptah Bridge with both Jira Cloud and any versions of Jira Server/Data Centre.
Though Jira Server will no longer be supported by Atlassian from Feb 2024, we will still provide support for the customers connecting Ceptah Bridge to JIRA Server to the best of our abilities.
Ceptah Bridge works with projects stored in any version of Microsoft Project Server and in Project Online. It also works with resources from the Global Resource Pool and can synchronise Enterprise fields. You will need Project Professional (Desktop Client) to use Ceptah Bridge with the server products.
Project Professional is included in Project Plan 3 and Project Plan 5 Project Online subscriptions.
