To archive the 6.0 server,
msdeploy -verb:sync -source:webserver60 -dest:archivedir=c:\mymagicdir
To instantiate the new 7.0 server,
msdeploy -verb:sync -source:archivedir=c:\mymagicdir -dest:webserver60
That should be it. Note:
1) If you want to skip the content copy for some reason (i.e. just want to copy the configuration), add a "-disableLink:Content" to the command line on both commands.
2) The second command line is a little confusing since it still refers to webserver60. But it is intentional. When you run this command on an IIS 7 server, we will convert the metabase settings over to the new config system of IIS 7.
3) If you run a command with "-whatif", we'll just tell you what we would do. That might be useful for debugging purposes as you play with the tool.
Hope everything works. Let us know if you have any issues.
