The catalog file for Photoshop Elements 6 will remain as it is while upgrading it to Lightroom. You will be able to use Photoshop Elements6 in the same way.
(Assuming you have Lightroom CC or Lightroom 6 trail version) This version of Lightroom has not been tested with Photoshop Elements 6 as it is very old version.
Still you may try it and check.
Thank you Mrinmay. I will go ahead and try it.
I went ahead and tried. It worked but with some problems. Only a few of the files came across with images. Had file name but no connection to the image for almost all. But what did work was to got to the first image in each collection and click on "photo is missing" then click on "locate" When I located one image in a collection, Lightroom then proceeded to find most of the rest of them without any help. A bit cumbersome but it is getting the job done.
Thank you for the update.
Glad to hear that the issue is resolved.
