Prior to touch the live servers I thought to simulate the exact scenario in test environment.
Tasks: Upgrade both servers to domino 7 , one by one, start with server 1 first.
Scenario: I have server 1 and server 2 both running 6.5.5 on windows 2000 as partition servers on single physical machine , both are clustered with each other .
Server 1-> domino1 & data1
Server 2-> domino 2 & data2
Problem : When put domino 7 CD and try to run setup , during installation it prompts for domino and data directory so I directed to use domino1 and data1 respectively.
It successfully finishes installation but I was amazed to see that it tried to uninstall previous version of notes version then finish installation of 7.
Thereafter, I ran server 1 again and it prompted for upgrading domino directory as per normal and I said ‘YES’ to proceed.
Everything normal and server 1 now work as 7 but realized later that server 2 gone. I cannot run server 2 anymore.
Questions : 1- How to prevent un-installation ?
2- What went wrong in the whole process?
Ur expert advice will help me to prevent this problem to occur in live environment.
