Upgrade or Replace ColdFusion 9 and 7

I'm tasked with installing Cold Fusion 9 on a box that already has Cold Fusion 7 on it.  They really want to have them running side by side.

I have a few questions on this, and I'm hoping community support could help guide me in the best direction.

1) From what I have read it is highly suggested to run only instance of CF on a server.  Can anyone further prove or dispel that suggestion?

2)  I have the tag changes since version 5 and above as my first resource link below.  If we would move to strict CF 9, should it be relatively easy to upgrade?

3) If I was going to have CF 9 and CF 7 run silmuntaneously on the same server it was suggested to install the new version first, and then the old version.  Well this server already has CF 7 running on it.  I don't think it would be wise to uninstall CF 7 just to install CF 9 first.  Do you agree?

4)  If the versions were running side by side, what is the indicator that says one site or app runs which version of CF?  My initial and limited experience with CF 9 is that it is site based.

Any other help or guidance on this issue?

Thanks,

    I don't know who has been suggesting that, but I know lots of people (including us) run multiple instances of CF on a server.  Running multiple instances of different versions of ColdFusion is a bit more difficult, but quite possible.

    Relatively easy, yes.  But not easy enough that you won't want to do the upgrade in a development environment first and thourghly examine your code base before doing this in production.  One of the biggest gotcha is having User Defined Functions (UDF) in the code with a function name that is now a built in function in the new version.

    It is quite possible to have multiple versions of ColdFusion running side by side.  But one must plan for it from the beginning.  In order to do this, you have to use the "Multiple Server" configuration of a ColdFusion Enterprise (or Developer) licensed ColdFusion installation.  If your CF 7 is not this, if it is the highly common choice of an Enterprise Standalone or a Standard ColdFusion license, you will need to uninstall it and reinstall it in the "Multiple Server" configuration.

    This is done through the web server connectors.  It is quite easy to define a spefic ColdFusion instance and connect to to a specific Web Server site.  The GUI Web Server Connector tool makes it pretty darn easy to set up.

    Can you tell if it is in "Multiple Server" configuration from this?  If not where can I find that information?

    No, but I can tell it is an Enterprise edition, so it is at least possible.

    When you open the ColdFusion administrator.  Do you see an option at the bottom of the left menu manager for "Instance Manager"?  If you do, you have a multiple server confguration for ColdFusion.

    You can also tell by where ColdFusion is installed.  C:\ColdFusion (or something like that) and you have Standalone, C:\Jrun4\servers\cfusion\ and you have Mulit-server.
