Hi @iamnarendrasingh !
Based on my experience, you might encounter a few issues with forms when upgrading to a newer version of Enketo.
For example, in one of my deployments, I was using ODK Central v2023.3.1 and decided to upgrade to the latest version. After the upgrade, I noticed that some of my forms - particularly those using auto-populating repeat groups - stopped working with Enketo. The newer Enketo version didn’t load repeat groups when trying to edit such a saved form, whereas the older version handled them without any problems.
It’s important to note that this isn’t an issue with ODK Central itself but rather with the Enketo version. Thankfully, I was working in a development environment during this upgrade and kept my forms and data intact in the production setup. This saved me a lot of trouble.
If you’re planning to upgrade, I’d recommend testing in a development setup first to ensure compatibility with all of your forms.
Great Day!
