Server to Datacenter license upgrade


We are using Server 6.9.0 and plan to migrate to Datacenter

Looking at the documentation for current Bitbucket it seems that it is possible to do a seamless upgrade for the license.

Could you please confirm what is the minimal version of Server that supports seamless license upgrade?

Hi @Sergei Valevka , welcome to the Community!

This is a great question, as it's only been since more recent versions of Jira and Confluence that a simple license change was all that was needed to make those applications work as single-node Data Center instances.

Fortunately Bitbucket Server has always supported running as single-node DC without additional changes. You should be all set to convert with the license change on Bitbucket 6.9.

I would however suggest at least upgrading to 6.10 - which is a Long-Term Support release - if you are able to. 6.10.13 was released about a month ago, and 6.10 as a line will be supported through next January. For more information about Long-Term Support releases, check out our documentation describing them and our support policy around LTS releases. The latest LTS version of Bitbucket Server is 7.6.

Thank you @Daniel Eads , really appreciate the answer

Once we update the license, the plan is to deploy a new Datacenter instance v7.16 and migrate our data from 6.9 instance to the new instance.

I was looking through the documentation and the only migration document I could find is the one below. Could you please confirm that it is suitable for migration between 6.9 Server and 7.16 Datacenter. Thank you!

Yes that's essentially the process! Once you're ready to add new nodes, Set up a Bitbucket Data Center cluster is a good document to work through.

The biggest got-ya is that MySQL can't support multiple Bitbucket nodes - therefore we recommend that you do not use MySQL even for single-node Bitbucket Data Center. The supported databases for Data Center are listed on the Supported Platforms page.

Thank you @Daniel Eads 

We don't plan to have a cluster yet. Am I right in thinking that to install Datacenter on a single node, I use the latest binary for Server from and then provide Datacenter license during the install?

Daniel Eads Atlassian Team Sep 17, 2021

Yes, that's right. The binaries are the same for both Server and Data Center installs; it is the license key only that determines if the install will become a Server or Data Center instance. That's the right link for the downloads!
