We are having connector which will connect NetSuite ERP system using SOAP web services.
As we know NetSuite is Cloud based ERP system so to access this we login using NetSuite URL : https://system.netsuite.com/pages/customerlogin.jsp
Now I assume that, this is Cloud based system and they update there system for all its user
Example: 2019.1 for all NetSuite customers
Now some of our customers are saying there NetSuite version 2018.1 or 2015.1
Is it possible ? as this is cloud based system
I have gone through NetSuite help community but didn't find any answers there
