HTML to Plone
ReTrans wanted to merge their public facing site into Plone, which is where the company intranet runs, to make page and content change management easier. They decided to consolidate on Plone 'for more functionality related to customer and internal applications.'
The existing site was static html. All pages and content were recreated in Plone and the existing static theme was quickly converted for Plone with Diazo. Diazo is a tool that makes it very easy to turn any static theme into a dynamic Plone theme.
Liferay to Plone
Six Feet Up saved a significant amount of time by utilizing Transmogrifier to migrate SFARI's legacy content via scripts rather than transferring by hand. The Foundation had been powering their old site with Liferay, which was backed by a MySQL database. Thanks to Transmogrifier, Six Feet Up was able to dump the content out of Liferay and pull it into Plone and its ZODB database while maintaining as much of the original content configuration as possible.
