    Hi Gaurav !

    1. Go through the release notes of older version(which you are migrating from) and 18.3 and have a look on the deprecated & removed features/functions/smart services.

    2.Hope you will not be using any one of deprecated / deleted features as in old version, and if so then you need to upgrade your code / configuration.

    3.Once the upgrade is done, perform End-to-End testing of every application in 18.2 environment to make sure that the applications are not impacted.

    Please refer the Migration guide and it is very useful to apply the upgrade. Here is the link.

    Hope this helps.

    Thanks,
    Ravi.

    HI ravir0001

    The Envrionment is already upgraded to 18.3 version while the application was built on 17.1.

    When I debugged the process models i found that few old functions are used. Due to which process are getting aborted.

     

    i.e: 

    a!httpQuery(

                   url: "maps.googleapis.com/.../json",

                   queryParameters: {

                     a!httpQueryParameter(name: "address", value: "ABC"),

                     a!httpQueryParameter(name: "key", value: "XYZ")

                   }

                 ).result.body

     

    Now its asking to create some integration for this.

     

    Kindly Suggest
