Seamless work and immediate change in remote Jiras
Use all common practices of an agile board: drag-n-drop to change status, log work, adjust estimates, etc with the immediate change of source issues. WatchTower operates on data directly from source Jira.
Compare original and migrated content at one board to ensure consistency. For Enterprise level migration WatchTower can allow part of your projects be migrated to new Jira while still finishing the rest in old Jira from one board.
