ok so we have 3 environments (DEV/TEST/PROD) and i upgraded DEV to 7.5 sp1 a while back testing everything for us to upgrade as not all solutions were available. Now all are available but I ran into a problem.
I had our DEV server rebuilt (VM) and started the install. All went well as it even allowed me to use the old database (which was 7.5 and im installing 7.1). I received an error later stating couldnt configure database and I figuered most likely the schema is different. I had our SQL guys remove the old database and I go into SIM. I click Reconfigure and it goes and just errors. I have uninstalled and reinstalled. I got the readiness check and all looked good but I am not getting the screen telling me the sql server, https ports and all that.
How do you totally restart the installation (without redoing server)?
