If you made any customization to the server.xml file, you must migrate those changes in the bitbucket.properties file in your existing Bitbucket home directory.  The bitbucket.properties file uses a slightly different syntax, so it is not merely a copy and paste procedure.

Read the page Migrate customizations from server.xml to bitbucket.properties and follow the instructions to migrate your customizations. Once your changes are migrated, proceed to the next step.
