Arcserve 2000 reinstall

Hello,
We have a backup server running Arcserve 2000 version 7.0 on a Windows 2000 Server. This Server needs rebuilding so I want to know what steps I need to take to rebuild the server and reinstall Arcserve. I do not have much experience with Arcserve so am hoping somebody can help.

I am hoping I can do an export of the jobs to a USB key and then import them back in when I reinstall Arcserve on the new rebuilt server.

Is there anyything else I ned to do which will make it easy for e.g. anything to do with the backup device.

Any help will be appreciated

P.S. I am looking at rebuilding to Windows 2003 as opposed to the current windows 2000

Cheers
Jeff
