Currently, there are two DataSync for ServiceNow (Core) user interface (UI) you can choose from. See below which experience fits you!
The He20 interface is a redesigned UI that improves your experience to better navigate through the features you use.
Starting with the Iodine 7.0.0 release, the He20 UI will be automatically applied to your ServiceNow instance.
Additionally, see the different form views available for bulk and dynamic shares with Switch form views.
The Legacy interface provides the look that dates back from the very first release of the Perspectium Core, Argon (1.0.0), to Gold (5.0.0).
Starting with the Iodine 7.0.0 release, the Legacy UI will not be accessible. If you would like to use the Legacy interface, contact Perspectium Support.
