Wanting to improve Lightroom Classic CC8.2 performance, I moved my Lightroom folder containing my catalog, backups, previews and smart previews to my desktop SSD from an external drive. All my photos remain on the external drive. I copied the folders with Windows Explorer. Lightroom Classic CC found my photos on the external drive. Everything looks good except that I no longer see any develop history in the Develop Module. The grid display in the Library module show icons indicating the photo has been cropped, edited, keywords, etc but the Develop module shows no history. I cannot figure out how to resolve this as I would like to see the history. It also appears that the SmartPreviews folder has not been touched since I moved the folders using Windows Explorer. I do not use the cloud or Lightroom CC. My pc runs Windows 10. I have backup files and I renamed the previous used files on my external drive in case I had a problem. One other thing to note: the Develop Module Histogram is showing "original Photo" and at least one of my photos is indicating Process Version 4 and has an option to update to current Process Version. Any ideas on how to proceed? Thank you!
