The Solution was to export and import data using APIs in POSTMAN:
The following example can be used for demonstration:
GET REQUEST:
https://YOURSERVERADDRESS/api/events.json?program=PROGRAMID&orgUnit=ORGUNITID&startDate=2021-01-01&endDate=2023-08-04&ouMode=DESCENDANTS&fields=programType,orgUnit,program,programStage,event,status,orgUnitName,eventDate,lastUpdated,created,dataValues&pageSize=3000
Clean your data and import using the following API
POST REQUEST
https://YOURSERVERADDRES/api/events
