Hi,
I apologize for the delayed reply.
The question is, 5 instances means 5 instances on total, not for each version I install, isn't it? In my case, I set up 5 instances and when I reach the 6th installation, it only let me upgrade an instance, not install a new one. So I guess it's n instances in total.
Yes, 5 instances means 5 instances in total. After all 5 were installed, you can only manage those instances (upgrade, repair, remove), not install a new one.
The problem I have now is that if I have 2 instances installed, the first one at version 1.0.0 and the second one at version 1.0.5, and I want to upgrade the first one from 1.0.0 to 1.0.3, It tells me that there is a newer version installed on the machine, so I cannot install it. I know that it is weird to understand this scenario, because it is not usual to install a 1.0.5 when you have installed a 1.0.9 installed, but now it is a requirement, and I need to know if it is possible or not. I tried to specify a minimum version 1.0.0 and maximum with a blank value on upgrade section, but it still doing the same. It is not critical at all, it is just to know if it is possible to do it.
I'm afraid this is a limitation, indeed. If an instance was updated to a newer version, another instance cannot be updated to an older one.
If you have other questions, just let me know.
Best regards,
Eusebiu
