We took the Sitefinity CMS offline on 7/30 for a core system upgrade; it should be available to the users who are part of our staging pilot later today (about 12 people).
We knew upgrades are part of the Sitefinity ecosystem; our colleagues in Family Medicine have used this CMS for a few years and they had given us a sense of what to expect. Every good tool needs to evolve.
However, because so much work has gone into getting us to this point, we were a little leery of launching a new version. After a demo session about it, the benefits looked pretty significant. Even better, the update work has gone very well: the system is running faster, we have better support for ASP MVC 5 and .NET 4.5, and a number of new, very slick MVC-based widgets have been added. The upgrade made sense now, during the pilot and before we had a hundred new users.
Updates are part of our contracted service and we anticipate significant ones will come along at least annually. Once we are out of the build phase and operational, we envision those upgrades going through IS and following the sorts of protocols we use for other applications.
