We have had quite a few users ask about what order ProjectWise should be uninstalled and then what order to do the installation. The implementation guide explains what components to uninstall although I had a particular case where the user didn't have every module installed and I notified him how to do it.
The implementation guide also implies that the Distribution Server be installed on a seperate server but doesn't directly say that so this also can be confusing for some users. Most of our users install ProjectWise Distribution Server on a seperate server so performance does not degrade on the Integration Server.
The implementation guide has the user uninstall in the following order. Make sure when doing the uninstall to delete the ProjectWise directory after all of this is uninstalled.
— ProjectWise Distribution Service Plugin for ProjectWise InterPlot Server — ProjectWise Distribution Service Administrator— ProjectWise Distribution Service— ProjectWise Automation Service Administrator— ProjectWise Automation Service— ProjectWise Design Compare Utility— ProjectWise Publishing Gateway Service— ProjectWise Publishing Server— ProjectWise InterPlot Server— ProjectWise Web Server— ProjectWise Administrator— ProjectWise iDesktop (if installed on server)— ProjectWise Explorer (if installed on server)— ProjectWise User Synchronization Service— ProjectWise Integration Server— ProjectWise Caching Server or Gateway Service— ProjectWise Orchestration Framework Service
As for the user's particular scenario, they had the following on their server.
Orchestration, Integration, User Synchronization Service, ProjectWise Administrator, ProjectWise Explorer.
I had them uninstall ProjectWise Administrator, ProjectWise Explorer, User Synchronization, Integration, and then Orchestration, delete the ProjectWise directory on the Server and then run CCleaner to get rid of any ProjectWise remnants.
In order to install, I had them reverse this and install everything from the bottom up depending on what modules they are planning to use, if they didn't plan to install a certain module on this list like caching and gateway, then skip it and move to the next module.
I have tested this in a VM and everything went smoothly.
