I have a Sharepoint 2007 server that I'm setting up for a client. They have an old Sharepoint 2007 site collection that contains several web parts. They don't have the solution (sln) files for all the web parts, all they have is the deployed web parts on their old site and they only want to move some of the web parts (and content) not all of them.
Is it possible to backup the old web parts and deploy them in the new server (or similar to achieve the same result)? If so, could someone please advise on the best strategy for doing this.
(Note: I have been using Gary Lapointe's stsadm extensions (http://stsadm.blogspot.com/2007/08/stsadm-commands_09.html) for moving the content across, but there doesn't appear to be any commands for doing this with web parts.)
