How to upgrade to Doorgets 7.0

Hello Developers,

I would like to upgrade my Doorgets installation to 7.0. How can I do it best? Is that also the Doorgtes backend or do I have to do it manually.

Once a glitch is me this happened and I have to reinstall everything. The contents were naturally away.

Thank you in advance.

I find it very unfortunate that no developer reports and helps. I still have the Doorgets version v6 and would upgrade to v7. But how does an upgrade work, I can not find anywhere on the Internet. Thanks in advance.
