Greetings,
I Would like to work on this project.
I have setup fineract before, so I should be able to safely so the changes you need,without introducing problems.
I can also do development on my own fineract server. this way, we don't risk messing your production server. I will give you access to my fineract server, so you can confirm that my solution works, before I make the changes to your production server.
As for setting up 2 spare fineract servers, we will need to discuss this more, as I need to know your architecture e. g is the MySQL database running on a different server? I will be able to make sound suggestions after we have a little chat.
Looking forward to hearing from you.
regards
