We use IM on our XPe Farm. It works great for us. We have monthly updates on many of our applications and we schedule the package uninstall and install of the package during the night and so far (knock on wood) we have had no problems with this set up. IM (was formally called IMS in MetaFrame 1.8 days) was done very well in XP platform. I would not given a nickel to use the old 1.8 IMS system but XP IM is sweet. That is my recommendation.

However, we can forsee some regular minor or major upgrades for that application. What is the best strategy for change management? To keep applying application updates and patches on the current setup ? or save / restore a clean image by ghost for each server ( with W2k, metaframe XP installed ) and install new version of application from there? Is there any document for reference ? Best regards Raymond
