Re-publish an InfoPath Template to an existing list

Recently I made a goofed-up in a SharePoint list where an InfoPath form was published. As we all know that, if we publish an InfoPath form to a library, the next time onwards the publishing wizard remember everything and you only have to click next.


But when I try to re-published a similar template from a different site to an existing library, the metadata of that list are gone. Also I have figure out that the internal names of  "Promoted Properties" are also changed. Say, earlier we have a field called "Request" now it becomes "Request1".


To avoid these type of problem, you need to map the column when published.
