Greetings Folks,
Would like to ask your experience in upgrading ObjectDB from 2.6.x to to 2.9.x.
Any official upgrade documentation SOP?
What's the risk when we upgrading instances with large data sets?
Thanks in advance for your inputs on this.
Sai.
It’s good to see that a 10-year-old version of ObjectDB is still functioning reliably, but it’s definitely time to upgrade.
Because most users upgrade more frequently, there may not be much direct experience with the specific jump from 2.6.x → 2.9.x.
All ObjectDB 2.x releases are designed so that databases created in earlier 2.x versions can still be opened and used in later 2.x versions, and the API remains largely consistent. In theory, your existing applications and databases should continue to work after the upgrade (with the exception of BIRT reports, if used by your application).
However, any upgrade that spans several years may introduce subtle issues that are difficult to predict without testing. Changes in schema evolution, new features, or query behavior could cause unexpected behavior.
The safest approach is to make full backups of your databases, test the upgrade on copies of your largest datasets, and validate both application functionality and performance before rolling it out to production.
