Well I’ve had some time to look at our ArcSDE 9.1 and ArcIMS 9.1 and I’m not really sure if either needs to really be upgraded. I think I’ll upgrade ArcSDE because we don’t really do and direct programming with it so I’m sure ArcCatalog can connect fine and I’m sure our existing ArcIMS sites will still work find, but I’m at a loss about what I should do with ArcIMS 9.1. The only really updated part that interests me is support for Tomcat 5. We don’t use ArcIMS on Unix or Linux so its not a big deal that they are at the same level as the Windows support and I don’t really see anthing on ESRI’s site telling me that there is anything new with the .NET or ActiveX connectors. The WMS Connector is something we’ve looked at but its nothing we are currently playing with.

Both my ArcIMS installs are working fine so I figure lets just go with ArcIMS 9.0.x and not play with fire. The what’s new webpages are nice, but I’d love to see something like a changelog or more detailed writeups of what is new.
