Restoration after patch version upgrade

Hi Team,

I am planning to perform a patch version upgrade（from 8.6.4 to 8.6.6）, but if there is a problem after the version upgrade, I would like to switch back.

Is it possible to revert to the previous state after upgrading?

If possible, could you please tell me how to do it?

Hi @YutaI205: There are multiple ways to revert a upgrade. Some info below.

  • You can run reverse.bat or reverse.sh to revert a upgrade
  • If you are doing a out of place upgrade, you can fall back to your original DB in case of rollback
  • If you are doing in place upgrade, you can handle it in DB using backup (or) restore points for rollback
  • Changes other than DB like App server changes to be rolled back separately
  • Cases which are created in the new versions should be carefully considered during the rollback

It is always recommended to take a full backup of the database before upgrade.

Thanks.

Hi @ArulDevan.

Thank you for your useful information.

I learned for the first time that there is something called reverse.bat.

I would like to consider which method is the best to use.

Thank you very much.
