You can try:

1. In SSMS right click on the table and select 'Script as create'
2. In that script change names to use new names
3. SET IDENTITY INSERT OFF
4. insert into NewTable (list all columns)
select list All Columns from myTable

--- This is assuming you don't use some advanced features such as temporal table

Once you're ready to get back you would also need to use

DBCC CHECKIDENT ('MyTable', RESEED, MaxCurrentValue);
