In the past, we have installed different versions of the Cloverleaf client on Citrix. This has mostly been when we’re in the middle of an upgrade and need to have different versions for the test and production servers. You might want to think about using Citrix.
I do not know of any “portable” IDE between versions. The issue would be that the NetConfig formats or other formats of files may have changed between versions.
If you are just looking for Network Monitor information for support purposes, you will probably want to look at the Global Monitor.
I guess it depends upon what you are wanting that analyst to be able to do.
