We need to migrate Jira projects from a Jira Software Instance (Version 6.x ) to a new instance. What is the best strategy?
a) Should we create a new target instance at Version 6.x and migrate projects using plugin (i.e., Configuration Manager) and then upgrade to a target version? or
b) Upgrade the existing version to the latest/target version in the source instance and create the new target instance with same version as source instance then migrate the projects via plugin (i.e., Configuration Manager) or
Any other suggested way (Atlassian Best Practice)?
