Hi Avi Khetarpal
We are working on upgrade script to provide you easy migration from 3.0.x to 3.1.0 but scripts are not ready yet.
It will be available as soon as possible.
I advise you to please wait for new upgrade scripts.
Meanwhile, if you want to test new scripts you can try this one [link](https://github.com/GluuFederation/community-edition-setup/blob/upgrade_script_3.1/static/scripts/3031_Readme.md)
(please don't create support tickets for this scripts as these are under construction, not completed yet)
