Update instructions

Thank you I was able to update from v2.2.1 to v2.9.9 without and installation error.

When I try to upgrade to the latest version [2.9.8] using Extensions > Install, I get the following:

Warning
Extension Install: Another package is already using the named folder: /administrator/manifests/packages/vdata. Are you trying to install the same extension again?

Error
Error installing package

If this isn't how to update the extension please advise how this is done.

My subscription has not expired.

Joomla 3.6.5
PHP 7.0.16

Thanks so much.

Thank you. And where do I find the documentation on how to update the component?

Where do I find update instructions in the documentation for the vData component?
I do not want to automatically assume that you just install the new version over the old.
Also, where is the changelog for vData?

Thank you.
