We currently have SharePoint Foundation 2010 installed, and are planning to install a trial of Server Standard 2010.
If the Standard trial runs out, and management decides not to purchase Standard, and we have to revert to Foundation, will we lose content that is stored in site templates that are not available in Foundation? For instance, MySites, Enterprise Wikis, etc.
Best Answer
Yes. The content is in the content database and will continue to be there. Basically, you won't have easy access to it.
You could try migrating some of the lists and libraries, including wiki pages for supported page layouts, not Enterprise Wikis. The best way to do that is probably with a 3rd party tool, however. And, if you're not spending money on licensing SharePoint, you probably don't want to pay for a migration tool, either.
