I am currently using 0.79v (virtual box) of Bahmni and want to upgrade it to 0.90 but as this will delete all the modifications in the database as well as the settings i am not trying to install it.
But now as i have a RaspberryPi 3 sitting idle, thought of giving it a try.
Please let me know how to backup the openMRS database and the config files of openMRS and transfer them to centOS running of the RaspberryPi. I would need to install bahmni 0.90 first. I have still not done it.
