In my solution, I have two forms with the same structure. I pretend to move all entries from one form (old form) to other (actual form).

I executed the following queries via SQL to say to those records which have old key (from old form) and change them to new key (actual form).

--set new form key on old form records

update UFRecords set form = 'NEW FORM KEY' where form = 'OLD FORM KEY'

-- update RecordData field with new keys

update UFRecords set RecordData = cast(replace(cast(RecordData as nvarchar(max)),'034B9219-ADD1-4C6D-A6CD-DD1096802E0','9BB74648-80A9-4FC9-BE98-D808ABA2CB62') as ntext)  where id = 619        

--update record field -> this is done 4 times to 4 form fields

update UFRecordFields set FieldId = 'NEW Field ID', Alias = 'NEW ALIAS'  where record = 619 and FieldId = 'OLD Field ID' 

At moment, appeared news records in list of entries from actual form but the values returned as empty .

If I want to see more details from that record, doesn't show any value like you can see in this picture:

What could it be?
