As the subject mentions, I am upgrading my Xojo apps to use version 9.3.1. I don't see anything in the release notes that indicate I need to change my app in any way for this. I ran the app in the debugger using the new version and everything worked as expected.

I quit the app and reopened the database with my app that is still running version 6.3.2 and it worked fine - it appears there is full backward compatibility.

Am I correct that this upgrade is transparent? It has been a while since I upgraded a Valentina version and I was expecting that I might need to make some minor coding changes as I have with past upgrades. From my testing, it appears seamless.

I'm not complaining! This is great! I just want to be sure I'm not overlooking anything. To be able to jump 3 versions seamlessly is very nice!

Hello Steve,

Yes, the upgrade procedure is transparent and automatic, newer versions always open databases from older versions.
As for the opposite - it may not always work, so not recommended.

The one change that may affect SQL code used for older version - the use of [] for identifiers is prohibited now, so please always use double quotes, according to SQL standard.

Thanks for the confirmation and the tip on looking for [] in my SQL.
