You can use background script and either use standard GlideRecord +query + iteratation or GlideMultipleUpdate - doing the same but easier to do and (I hope) faster to use

var gMult = GlideMultipleUpdate('<table>');
gMult.addQuery('<field>', <value>);
gMult.setValue('<field2>', <value2>);
gMult.execute();

Hi,

for older records you need to check sys_audit table or sys_history_line table where previous information is stored.

Hi,

example below

if table is audited then you can do this

You can do GlideRecord from following tables,

sys_history_set and sys_history_line

var incident = new GlideRecord('incident');
incident.addQuery('u_first_assigned',''); // give correct field name here
incident.query();

while(incident.next()){

    var history = new GlideRecord('sys_history_set');
    history.addQuery('id',incident.getValue('sys_id'));
    history.query();
    history.next();

    var auditH = new GlideRecord('sys_history_line');
    auditH.addQuery('set',history.getValue('sys_id'));
    auditH.addEncodedQuery("field=assigned_to^newISNOTEMPTY^oldISEMPTY"); // new is not epmty and old is empty
    auditH.query();
    if(auditH.next()){

        incident.u_first_assigned = auditH.new_value; // give correct field name here
        incident.update();

    }

}
