Structure comes with a number of bundled synchronizers, but you can add another synchronizer to the system, allowing Structure users to install it on structures and run export / import.

Implement StructureSynchronizer

Create your implementation of StructureSynchronizer interface.

Define structure-synchronizer Module

Add Synchronizer Module module to your atlassian-plugin.xml, referring to your implementation of the StructureSynchronizer.

Test Thoroughly

Test how your synchronizer works when other synchronizers are also installed onto the same structure.
