Getting ready
The following things need to be checked before you start with this recipe:
- Make sure you have a valid Jira license.
- Check whether your new environment is compatible with Jira system requirements.
- Ensure that both the old and new Jira instances are of the same major or minor version. If you intend to run a newer version of Jira in the new environment, it is recommended that you upgrade once the migration is successful.
Migrating a system can be very disruptive for users. Make sure you communicate this to your users and allocate sufficient time for rollbacks.
