Photoshop Elements :: How To Maintain Configuration Of Current Catalog

While the Version Sets in my current catalog are collapsed, the version sets in the Catalog on the new computer have all become 'expanded'; this is unacceptable to me, as many of the pairs that are stacked as Version Sets have become separated.  While all of the Version Sets are "tagged", it looks as though many of the photos in the expanded sets are without tags.  Problem #2 is that the hierarchy of Keyword Tags that I currently use is lost when the Catalog is restored in the new computer's Organizer.  I currently use about 500 Keyword Tags, divided into 6 categories (i.e. People, Places, Locations, Events, Other, Bird Species).  On the new computer, the tags are alphabetized without being separated into their 6 categories.  I currently have close to 30,000 items in my Catalog, and have spent hundreds, perhaps thousands, of hours editing (and saving both the original and  edited files as  Version Sets), tagging and captioning all of my photos.  I followed the instructions previously published in "Photoshop Elements Help" regarding backup to an external hard drive and restoring the files in an empty Organizer on the new computer.  I also used the "Save Keyword Tags To File" command before the backup.  I do have the intact "current" Catalog on my old computer, complete with tags and captions, collapsed version sets, and a list of Keyword Tags organized in the Hierarchy that has worked best for me.
