Two-way Sync
With a two-way sync group, you can sync versions across a group of Jira spaces. We usually recommend the two-way sync because it covers most of the use cases.
Use Case: If you have e.g. three different teams (Dev, Marketing, QA) which work on the a software product and contribute to the same releases, you create a two-way sync group which contains all spaces.
Go to Version Sync in Space A: Space A > Space settings > Apps > Version Sync
Make sure that you are in the tab Two-way sync
Create a new group (e.g. PA) with default settings
Click + Add another space
Select the space you want to add to the sync group (e.g. Space B)
To add a space to a version sync group, ensure the following:
Your account has the Browse Projects permission in the space.
The space is not already part of another sync group.
> You get redirected to the Version Sync settings of Space B
Make the desired settings and save
If applicable, sync existing versions from Space B manually

Future version will be synced automatically.
