+# Reconfigure host url in DocSoft
+EDCenter can be operated as a SAAS or onprem solution. Depending on the variant, the host url of the EDCenter target server must be changed in DocSoft so that the measurement data is sent to the correct EDCenter instance.

+
+Default host url (SAAS): https://edc.int-tec.com/docsoft/

+   Options -> User level...
