I am seeking opinions on the portability to Portal server from using the built-in Windows sharepoint services. We have plans to install a company wide portal that we will also be extending to our service providers, however we are unlikely to start this project for another 6 months (which really means 8). In the meantime I would like to take advantage of some of sharepoints functionality built into Windows (e.g. set up a document library that links to our CRM installation). I am rather hesitant to do this as I do not want to lose the work that we do when we finally move to a full portal installation. Does anyone have an opinion on how easy it is to migrate/upgrade between the two? has anyone done this before? Is there any good documentation out there on this subject? TIA Saira
