I am using Lightroom 5.6 and have multiple plugins installed. These include Nik filters, Photomatix, DxO Optics Pro and DxO View Point. I would like to upgrade to Lightroom 6 or Creative Cloud. Would the new version of Lightroom automatically recognise and plugins during the installation process or will I need to reinstall them one by one?
When I moved from Lightroom 5 to Lightroom CC the Nik plug-ins were in place. I have a printing utility that came with my printer that didn't transfer automatically. But although it was required was to copy the folder from the Lightroom 5 folder to the new Lightroom CC folder. I can't speak for all plug-ins because I don't use a lot.
