Updated Component Installation

Is it possible that an updated component version doesn't truncate the db tables that were created in previous versions?

If so.. is there a parameter to be set or a line to be hacked somewhere to update all of the necessary elements but not the data?

Thanks

This one needs an answer. Given that we are now faced with re-generating and re-installing to deal with Joomla 3.7.1, this becomes very important.

Hi there
So premium users doesn't have to uninstall or install and they shouldn't lose data just by updating a component.
Hope this clarifies the issue.

Crystal clear. Moving on...
