How to reinstall add-ons after re-installing Confluence?

[johan iojo]

I recently un-installed and re-installed Confluence.

Next step I need to do is to re-install also all add-ons I was evaluating. 

But i cannot find a 're' install option: each time, the add-on is installed and a new license key is generated. But i would like to use the license key i already have. 

How to do this?

Apply you licence directly in your confluence Manage Addon's page.

Expand desired plugin and in the bottom you'll find License key with pencil. Click there and paste your own key.
