1. I have a Windows Server 2003 machine with IIS 6 which currently holds everything. I need to migrate everything to a Windows Server 2012 machine with IIS 8. Will using the same set of instructions as migrating to IIS 7 work? Such as the instructions from
2. My second question. Will using the Web Deploy utility remove everything that is on the old server or will everything be on the old server as well as the new server once I use this utility and migrate everything?
Thanks for the help.

For this migration issue, it's recommanded to use
Web deploy to migrate a Web Site from IIS 6.0 to IIS 7 or above,
IIS6 was released in Windows Server 2003 over 10 years ago. Apps used the ISAPI pipeline. By its nature everything in IIS6 is what we think of today as "classic mode," rather than the newer
Integrated Pipeline in IIS7.
IIS7 and 8 were re-architected with the superior and faster Integrated Mode pipeline but retain "Classic" mode for compatibility.
If you're moving an older app from IIS6 (which by definition was only "classic" mode) to IIS 8, the best near-term decision is to run in Classic Mode on IIS8. Classic Mode is
fully supported so you aren’t doing anything wrong by running in classic mode. It's a mode that is there for a reason.

Thanks for the reply Angie
What about after the migration using Web Deploy? Will everything still be on the old 2003 Server and also on the new 2012 Server.... or does it get completely removed from the 2003 Server and is now only on the 2012 Server? Thanks.

Nothing gets removed when you migrate (you don't want it to) so the WIndows 2003 machine will be as is.

can the web deploy tool be used while the server is in production and not effect live websites?

Yes, no problem there.
