upgrading confluence getting failed

[shrikant maheshwari]

Hi team,
I am currently using confluence 6.5 and trying to upgrade to 7.4. But the upgrade is getting failed.  After the upgrade is done successfully and after hitting the confluence URL i am getting redirected to the below page. And i am not getting any other option to proceed. I dont want to set up confluence in the cluster mode, could someone please suggest why i am getting redirected to configuring cluster page.

This page is triggered when you're setting up a Data Center node, not upgrading a Server Jira (although you may get it if you're upgrading an improperly configured DC node as well)

It's not a failed upgrade, you can fill in the questions it asks for and carry on to the rest of the configuration.
