we say that in the version changes you have to do them with a little attention;it would be interesting to know how long a machine lasts on average because of updates and how much time you lose to "laugh" it because of a version change.
normally any update requires only permissions then think of it alone to delete, edit add files.
if I have to install a new version, instead, some extra shortening to do is there. for example clean the superfluous and then install the new version without finding any residue... or install the new and, once consolidated, remove the previous one.
Obviously if installing versions as if they were upgrades it is a matter of time before the cad gives problems.. .
