While using celigo we get a message to install SuiteApp in the Netsuite account, Without installing Celigo integrator.io on Suitescript 2.0 we can’t run new flows with the new Netsuite Connection, and also with the Old Netsuite Connection.
Oracle NetSuite encourages you to transition from using SuiteScript 1.0 to using SuiteScript 2. x. If you are using SuiteScript 1.0 for your scripts, consider converting these scripts to SuiteScript 2.0 or SuiteScript 2.1. SuiteScript 1.0 scripts continue to be supported, however, SuiteScript 1.0 functionality is no longer being updated, and no new feature development or enhancement work is being done for SuiteScript 1.0.
In general, SuiteScript 2. x provides support for all functionality in SuiteScript 1.0. However, there is not always a direct mapping between functions and objects in SuiteScript 1.0 and modules and methods available in SuiteScript 2. x.
SuiteScript 2. x is a modular language, there are several general differences between how scripts are written in SuiteScript 2. x and how they are written in SuiteScript 1.0.
