We are C# shop (and just starting with TFS) with number of different solutions (and there are lot of them) that represent different components, that we deploy on fairly large number of production servers. Currently, component installations are done manually, where developer would go on each server and install/de-install component (components installation files are .msi, that we create using WIX for each individual component). Of course, problem becomes that eventually someone will forget to install a newer component on production servers and only after going through the other servers, you will find out that you are dealing with outdated component. And we are terrible at keeping track of what did what the servers.
Technically, we can place all existing solutions under one solution and have a single .msi - install file that encompasses entire range of projects. But this will create one massive solution and one massive MSI file. Though, this is clearly solves all the problems.
So what are the ways to version deployments of different software as one piece ?
