Hello All,
In our environment, PostgreSQL is currently running on lower versions, ranging from 9 to 11. We are planning to upgrade to the latest version, and I have a few questions regarding the process.
What are the key considerations or checks we need to perform before the upgrade?
Can we directly upgrade from version 9 to 15, or is a step-by-step upgrade required?
How should we handle extensions during the upgrade process?
What challenges or issues should we anticipate during or after the upgrade?
If anyone with experience in upgrading Postgres, please share your guidance.
Regards,
Naren
