Standard importers break your data.
We preserve it.
Author Preservation
Most importers map comments to 'Admin'. We map them to the original authors using email matching.
Status Mapping
We map your complex Jira Workflows to Linear States, ensuring no ticket gets lost in limbo.
The 'Safety Net' Sync
Includes 3 months of bi-directional sync. Run Jira and Linear side-by-side until your team is ready.
Executed by Experts,
not Bots.
