Is there an easy way to move to Lightroom Publishing Services to keep previous setup intact when moving to a new computer?
If you’re using the TTG Lightroom Publisher now, then as long as your working from the same catalog, it should work the same as it does now. You’ll need to make sure the plug-in is installed.
Further on moving Lightroom, whenever I need to move Lightroom to a new computer I always copy the Lightroom\ folder where all the presets, etc. are kept. I then just copy that folder back in to its proper location after installing LR in the new computer.
The location of this folder depends on your OS, but you can find it by going to the Lightroom Preferences > Presets tab and clicking on the “Show All Other Lightroom Presets” button.
