The biggest concern in doing this will be the difference in sys_ids of the domains. I am not sure, it will work or not, but you can give it a try -

1. Go to sys_domain table and export the table in xml

2. Go to domain_contains table and export the table in xml

3. Import both the above xml in another environment

4. You can go to any domain separated table in previous environment and export few incidents and import in the second environment

5. Most probably the domains should be right

let me know if it worked or not

Hi Srikanth,

With Step 1 i have successfully migrated domains from one instance to another. I am also able to them under Domain map.

That will be huge amount of data. Servicenow advices its better to use schedule import, in that way you can just run everything in the background and still can work on the target instance -

Importing from Another ServiceNow Instance - ServiceNow Wiki

Please make sure, you never miss this step listed in the link -

before transform script

if (action == "insert"){target.setNewGuidValue(source.u_sys_id);}

Mark if it is helpful

Hello,

You can use the Precision Bridge tool to migrate your data between domain separated instances so that the data is moved into the correct corresponding domain and all data integrity is maintained.
