Each time I install a new version of my component I have to delete the old one first which also deletes the database.
Could there be an option to save the database between installs or perhaps an option to keep the old database?

Looking ahead, if I want to add a feature to my Cook component I would not want to loose any existing data.

Of course, I understand.


On 1.6 or higher it is possible.
On 1.5, joomla first check if folder is used.
