Thus, I am asking this: Is it safe to downgrade from 9.5.4 to 9.5.2 by simply replacing the binaries? We will keep the data folder same.We are currently running at 9.5.2 and plan to upgrade to 9.5.4, but our change requirement needs to plan for a downgrade with data preservation, before upgrade is authorized.
Technically, that should not be a problem. The only thing to foresee would be that, if you are upgrading to fix any BUGs or CVEs, then downgrading would revert the fixes.
Just curious to know - when you say downgrade, do you mean to say there has to be a back-out plan in place if the upgrade fails ? or you are really going to downgrade again ?
