I have Parallels 13.2.0 on my Mac (MacOS 10.13.6). I use it to run an older version of MacOS so that I can open old documents, etc., but I do not use it very often and therefore at the moment feel that I cannot justify updating to Parallels 14. I would be grateful for advice about the relative merits (e.g. in view of forthcoming upgrades to the Mac operating system and anything else relevant) of sticking with Parallels 13 or changing to Parallels Lite.
