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.
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.
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 ?
