Have: System: Windows Server 2003 Std, IIS, SQL Server 2000. Existing: ColdFusion MX 6.1 (CF6) installed -working fine. Added: ColdFusion 9 (CF9) as its own web server so not to have clobbered my CF6's cfdocs and CFIDE directories, and CF9's CFAdmin works on port 8500. Also: Configured same datasource for CF9. Need: What steps do I need so I can toggle between CF6 and CF9 by only port number? I'm testing how CF9 and CF6 deliver the exact same page / website. Example (spaces added to prefent formatting funkiness): http:// LOCAL-IIS-WEBSITE / index.cfm - CF6 http:// LOCAL-IIS-WEBSITE : 8500 / index.cfm - CF9 Sean
