May I suggest 'LR Backup'
http://www.photographers-toolbox.com/products/mdawson/tpglrbackup/ Not only does it backup the catalog, but also ALL the key configuration folders/files (which is more than just presets and templates) from your system. These can be located where ever you want and then used in migration....or
keeping another system consistent with changes made.

I agree.
Moving multiple set ups for collections and collection sets is a pain currently - a clunky workaround requiring exporting and then importing a catalog.
