Server to Datacenter license upgrade
Asked by Sergei Valevka:

Hi,

We are using Server 6.9.0 and plan to migrate to Datacenter

Looking at the documentation for current Bitbucket <https://confluence.atlassian.com/bitbucketserver/migrate-from-server-to-data-center-996641211.html> 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?

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](https://confluence.atlassian.com/enterprise/long-term-support-releases-948227420.html). The latest LTS version of Bitbucket Server is 7.6.

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!

author: Daniel Eads
body: Yes that's essentially the process! Once you're ready to add new nodes, [Set up a Bitbucket Data Center cluster](https://confluence.atlassian.com/bitbucketserver/set-up-a-bitbucket-data-center-cluster-996641208.html) 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](https://confluence.atlassian.com/bitbucketserver/supported-platforms-776640981.html) page.

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 <https://www.atlassian.com/software/bitbucket/download-archives> and then provide Datacenter license during the install?


author: Daniel Eads
body: 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!
