1. What is the issue? Please be detailed.
I installed ODK Central in 2022.I now want to upgrade to the latest version but I would like to know some of the errors that may arise from the upgrade!
See https://docs.getodk.org/central-upgrade.
Start by reviewing upgrade notes for all versions between your current version and the one you are upgrading to. You can skip upgrades and directly install the latest version as long as you make sure to follow all relevant upgrade instructions.
