Please follow the instructions in this Jira support article to migrate your team-managed project to a company-managed project. 

Additionally, we recommend paying special attention to the final section titled "Things to keep in mind if you migrate from team-managed to company-managed". The new, company-managed project, may require some additional setup if you have custom fields that you'd like to retain in the company-managed project. 

We understand that migrating from team-managed to company-managed projects in Jira can be a complex process, requiring careful planning to ensure a seamless transition. Our team specializes in Jira configurations and can assist you with this migration. We offer this as a fee-for-service engagement. If you're interested, please email us at support@ketryx.com.
