Copy user field value to SharePoint online site

Question

I have a user field in a list that has allow multiple user setting on. ie I can have more than one user in the field. I am trying to copy my User field data form on prem SP2016 site to online site. But nothing is getting copied. Same logic is working if I am running it for two lists in same site but in case of two different sites it is not working.

Below is the code I am using :

//To get form source list FieldUserValue[] users = null; users = (FieldUserValue[])item["User"];

//to copy on target list var listItemCreationInformation = new ListItemCreationInformation(); ListItem newItem = targetlist.AddItem(listItemCreationInformation); newItem["User"] = users; newItem.Update(); targetlist.Update(); ctx.ExecuteQuery();

Anyone having idea what might be going wrong.
